I. STATEMENT OF CASE
The protestant-appellant, Diller Telephone Company, challenges the third and last order of the Public Service Commission (PSC), which granted the request of the applicants-appellees, Henry Jantzen and Vern Jantzen, father and son, to receive telephone service from Lincoln Telephone and Telegraph Company rather than from Diller Telephone, and ordered the Jantzens to pay Diller Telephone $338.91 to cover the latter’s loss of investment. On appeal to the Nebraska Court of Appeals, Diller Telephone assigned as errors, in summary, (1) the PSC’s consideration of certain evidence in concluding that the Jantzens are not receiving and would not within a reasonable time receive reasonably adequate telephone service, and (2) the arbitrary and capricious nature of its third order.
*84 The Court of Appeals determined that Diller Telephone’s failure to timely file its protest waived its opposition to the application and that it was thus precluded from participating in the proceedings before the PSC. Accordingly, the Court of Appeals, without reaching Diller Telephone’s summarized assignments of error, directed the PSC to reinstate its first order, which had granted the application upon the payment of Diller Telephone’s loss of investment of $97.21 and a connection charge to Lincoln Telephone.
Diller Telephone thereafter successfully petitioned this court for further review. We affirm the judgment of the Court of Appeals, as modified.
II. SCOPES OF REVIEW
In an appeal from the PSC, an appellate court examines the record to determine whether the PSC acted within the scope of its authority and whether the evidence establishes that the order in question is not unreasonable or arbitrary.
Fecht
v.
Quality Processing,
Moreover, in reviewing a decision of the PSC, it is not the province of an appellate court to weigh or resolve conflicts in the evidence or the credibility of the witnesses; rather, an appellate court will sustain the decision of the PSC if there is evidence in the record to support its findings.
In re Application of Kilthau,
For purposes of reviewing an order of an administrative agency, competent evidence means evidence which tends to establish the fact in issue.
Wagner v. City of Omaha, supra;
*85
Shepherd
v.
City of Omaha,
Applications to obtain telephone service furnished in an adjacent exchange are governed by Neb. Rev. Stat. § 75-613 (Reissue 1990):
Upon the completion of the hearing on such an application, if a hearing is required, the [PSC] may grant the application, in whole or in part, if the evidence establishes all of the following:
(1) That such applicant or applicants are not receiving, and will not within a reasonable time receive, reasonably adequate exchange telephone service from the company furnishing such service in the exchange service area in which the applicant or applicants reside or operate. The fact that an applicant is required to pay toll charges for long-distance telephone calls to an exchange service area adjacent to the territory in which the applicant resides or operates shall not be deemed to constitute inadequate exchange telephone service from the company furnishing such service;
(2) The revision of the exchange service area or areas required to grant the application will not create a duplication of facilities, is economically sound and will not impair the capability of the telephone company or companies affected to serve the remaining subscribers in any affected exchanges;
(3) The community of interest in the general territory is such that the public offering of each telephone company in its own exchange service area involved should include all the territory in its service area as revised by the commission’s order; and
*86 (4) The applicant or applicants are willing and will be required to pay such construction and other costs and rates as are fair and equitable and will reimburse the affected company for any necessary loss of investment in existing property as determined by the [PSC].
As the foregoing statute controls the adjudication of this matter, the appeal in part presents issues of statutory interpretation, which are questions of law, in connection with which an appellate court has an obligation to reach an independent, correct conclusion irrespective of the determination made by the court below. See,
Fecht

Lutheran Hosp. & Homes Soc.,
III. FACTS
The father had, in 1974, 1975, and 1976, unsuccessfully attempted to have the service changed to Lincoln Telephone. The Jantzens filed the application presently under consideration on December 18, 1990. Notice of the filing was published on December 20, 1990. Diller Telephone filed its protest on January 23,1991.
The evidence developed at that hearing establishes that the father lives 2 miles east and 2 miles south of Plymouth, where he has farmed since 1953. This home farm receives telephone service through Lincoln Telephone’s Plymouth exchange. In 1974, the father purchased a second farm which is separated from the home farm by a “mile of ground or a mile of road” and is located 1 mile south and 1 mile east of the home farm. Notwithstanding that the second farm has a Plymouth address, is in the Plymouth fire district, and is located closer to Plymouth than to Diller, it is served by Diller Telephone’s *87 Harbine exchange at Diller. A Lincoln Telephone cable is buried 108 feet north of the telephone service entrance to the second farm, while Diller Telephone has a cable 324 feet east of the service entrance.
The father testified that in 1988, the son moved into the house on the second farm and that he and the son began farming together. The numerous problems and expenses associated with conducting a single farm operation through two separate telephone companies caused this most recent application for a change in telephone service. Because of the expense of communicating between the two farms, calls are made on only a minimal basis for either business or pleasure. The father testified that as the son assumes more management responsibility, the two will need to communicate more.
The son testified that his primary reason for filing the application is to avoid toll calls. He further testified that his primary community of interest is with the Plymouth exchange. He pointed out that there is no bank, machinery dealer, county government office, veterinary clinic, or medical care service available to call in the Diller and Harbine exchanges. He also indicated that he carries on transactions with every business located in Plymouth. Of the 128 members in the son’s church, 125 are Lincoln Telephone customers, while only two other than himself are customers of Diller Telephone.
William Sandman, Diller Telephone’s manager, testified that Diller Telephone would suffer a $1,261.21 loss of investment if the application is granted, pointing out that Diller Telephone has upgraded the service it renders since the issue was last litigated before the PSC in 1976.
Diller Telephone opposes the application because it cannot afford to lose any customers. Sandman explained that because Diller Telephone is small and has a limited customer base for growth purposes, each customer is important; the departure of any customer could have a significant revenue impact made up by remaining customers.
The PSC then entered its first order, finding that the Jantzens were not receiving and would not, in a reasonable time, receive reasonably adequate telephone service from Diller Telephone and that the change in service would not create a duplication of *88 facilities, would not impair the capability of Diller Telephone, and was economically sound. In addition to requiring the Jantzens to pay Diller Telephone’s loss of investment, the PSC required them to pay Lincoln Telephone the construction charge of $ 1,460 to connect the facilities.
The PSC next granted Diller Telephone’s motion for rehearing. At the hearing on the motion, the son testified that he wants to call people on the Plymouth exchange without being assessed a toll charge and to be able to make unlimited calls to the Beatrice exchange of Lincoln Telephone for a small monthly fee; both services would be available if he switched to Lincoln Telephone. He elaborated that the operation he conducts with his father is served by the Plymouth exchange of Lincoln Telephone, while his brother, with whom he is also a partner in a separate farming business, receives service from the Beatrice exchange of Lincoln Telephone.
He also explained that in addition to his church, medical services, and neighborhood ties to the Plymouth exchange, he is an alumnus of the Tri-County school and a member of its booster organization. He is one of only two members of that organization receiving Diller Telephone service; the remainder are serviced by Lincoln Telephone.
The son added that his telephone number does not appear in the Plymouth exchange, that sometimes people have difficulty finding him because he is listed in the Harbine exchange, and that even if they do locate him, they do not call him because it is a long-distance call.
The son also testified that the primary reason for his application had changed from the time of the first hearing, in which he stated his sole purpose was to avoid toll charges. He now explained that his primary reasons for applying for this change in service are to integrate the farm operation with his father and be able to communicate better and to avoid the problems that exist with people not being able to find him.
Sandman feared that the loss of 1 customer might lead to a loss of 10 customers, and a loss of 10 customers would be critical to the company; Diller Telephone has approximately 870 subscribers, 120 served by the Harbine exchange. He conceded, however, that the basic rate for service would not *89 change simply because one customer left its service.
Arnold White, an accountant, testified that in calculating Diller Telephone’s loss of investment at $1,261.21, he applied a depreciation value to the plant investments of the central office equipment and building, the span lines between the host and remote office, and the buried telephone cable route that serves one subscriber. That total was then divided by the number of subscribers served by the Harbine exchange to get a cost per individual subscriber. White then added a cost for retirement of the plant.
White testified that granting this application would not be economically sound and that eventually, future revenues lost by the departure of the Jantzens and a series of other such subscribers could result in increased rates.
Norm Osland, president of the Nebraska Telephone Association, testified on behalf of Diller Telephone that both his organization and the Rural Electrification Administration are committed to maintaining franchise boundary integrity. The administration’s loans to Diller Telephone and other small telephone companies are based partly on those boundaries.
The PSC then entered its second order, which denied the application, finding that it had initially miscalculated Diller Telephone’s investment loss and, further, that the Jantzens had failed to meet the statutory requirements for a change in service.
The Jantzens thereupon filed a motion for rehearing, which resulted in the PSC’s third order, as described in part I above.
IV. ANALYSIS OF COURT OF APPEALS’ RULING
Our first task is to determine whether the Court of Appeals was correct in ruling that Diller Telephone had waived its opposition and was thus precluded from participating in the proceedings before the PSC.
1. Rules Not of Record
The opinion of the Court of Appeals sets forth certain PSC rules of procedure which are not part of the record. We have held that because establishing the existence and contents of a particular administrative rule or regulation at any given time is often a difficult and uncertain process, it is an established
*90
principle of appellate practice that, as a general rule, a reviewing court will not take judicial notice of the internal operating rules of administrative agencies. See,
Dairyland Power Co-op v. State Bd. of
Equal.,
2. Rule of Record
However, because the record does include the PSC’s statement of its rule of procedure requiring “protests to be filed within thirty days of the date of publication of notice,” we are able to consider whether Diller Telephone’s protest, filed on the 31st day after notice of the application was published, enabled Diller Telephone to participate in the proceedings.
(a) General Considerations
In certain circumstances, administrative agencies are permitted to depart from their own regulations.
Sun Oil Company v. Federal Power Commission, 256
F.2d 233 (5th Cir. 1958),
cert.
denied
Most courts which have allowed departures from agency rules have found that the violated regulations were intended to govern agency procedures rather than to protect any interest of the objecting party. See, American Farm Lines v. Black Ball, supra; National Labor Relations Bd. v. Monsanto Chemical *91 Co., supra.
Where the rules of an agency require certain information to be filed before a matter or rate can be considered, the agency’s discretion to waive the information will not be reviewed. In American Farm Lines, a motor carrier’s request for temporary operating authority with the Interstate Commerce Commission was granted despite the argument of competing carriers that the filing violated commission requirements. The U.S. Supreme Court ruled that the commission’s decision to relax its filing requirements was not reviewable; the rules were promulgated for the purpose of providing the necessary information for the commission to reach an informed and equitable decision and were not intended primarily to confer important procedural benefits upon individuals in the face of otherwise unfettered discretion.
Likewise, the U.S. Court of Appeals for the District of Columbia Circuit refused to review the waiver of the rules requiring a carrier to supply the Federal Communications Commission with information necessary to determine whether the investigation and suspension of proposed rate increases should be ordered in
Associated Press v. F.C.C.,
The applicability of an agency’s discretion in waiving a regulation turns on whether it was intended to aid the agency or, instead, to benefit outside parties.
City of Fredericksburg, VA.
v.
F.E.R.
C.,
Many courts will review a waived rule or regulation only upon a showing of substantial prejudice to the complaining party. See,
Onslow County, N.C. v. U.S. Dept. of Labor, 774
F.2d 607 (4th Cir. 1985) (agency regulations not mandated by federal law are not entitled to degree of judicial deference and enforcement due those promulgated under compulsion of law);
Mississippi Valley Gas Co.
v.
F. E. R. C.,
Procedural challenges to the filing of late petitions and motions in violation of an agency’s rules have, for the most part, failed. In
Dana Corp. v. I.C.C.,
However, in remanding for further proceedings a $500 attorney fee award granted in violation of the agency’s own regulations requiring a complete statement of the extent and character of work done, the same federal circuit court stated that in the absence of a reasoned determination that in a given case the ends of justice require a departure from an agency’s regulations, they must be observed.
Matthews v. Walter,
Courts have also upheld the discretion of agencies to accept applications filed past the submission deadline. In
National Labor Relations Bd. v. Monsanto Chemical Co.,
In Montship Lines, Limited
v.
Federal Maritime Board,
A framework for the review of an agency’s deviation from its own regulations was given in
American Farm Lines
v.
Black Ball,
(b) Nebraska Precedent
Although we have not heretofore determined whether the failure to file a timely protest waives the right of the protestant to participate in an agency proceeding, the Court of Appeals mistakenly cites
Douglas County Welfare Administration v. Parks,
Generally, rules and regulations of an administrative agency governing proceedings before it, duly adopted and within the authority of the agency, are as binding as if they were statutes enacted by the Legislature. Likewise, procedural rules are binding upon the agency which enacts them as well as upon the public, and the agency does not, as a general rule, have the discretion to waive, suspend, or disregard, in a particular case, a validly adopted rule so long as such rule remains in force. This is true even though the adoption of the rule was a discretionary function, and plenary powers, or powers resting in the absolute discretion of an agency, may thus be rendered subject to procedural limitations. To be valid, the action of the agency must conform to its rules which are in effect at the time the action is taken, particularly those designed to provide procedural safeguards for fundamental rights.
Id.
at 572,
In so holding, we rejected the appellants’ argument that the Joint Merit System Council could waive its own rules with regard to filing for an appeal and hear such cases as it desired. We found no authority for such a rule, nor any reason to consider that the rule setting the time for appeal was not
*96
applicable, particularly where the unexcused delay was for more than 3 months at the very least. See, also,
Nucor Steel
v.
Leuenberger,
Similarly, in
Douglas Cty. Health Dept. Emp. Assn.
v.
Douglas
Cty.,
The decision in
Parks
refusing to uphold the agency’s waiver of its own rule follows from the fundamental rights which the rule protected. The agency’s rule therein prescribed the time of filing of an appeal. Such time limits are jurisdictional. See,
State v. Flying Hawk,
The PSC’s discretion to allow Diller Telephone to participate in the hearings can be compared to a trial court’s discretion extending the time in which to file an untimely answer or reply. See,
Mason State Bank v. Sekutera,
Under Neb. Rev. Stat. § 75-612 (Reissue 1990) and § 75-613, the Jantzens were required, irrespective of whether Diller Telephone participated, to present evidence to establish their case. See
In re Application of George Farm Co., 233
Neb. 23,
Indeed, if Diller Telephone’s evidence had not been admitted, there would have been no information regarding its “loss of investment,” as required by § 75-613(4). Thus, not only was there no prejudice to the Jantzens in allowing Diller Telephone to participate, Diller Telephone’s participation helped the Jantzens make the necessary record.
Adopting and applying the analytical framework set forth in
American Farm Lines
v.
Black Ball,
Thus, the Court of Appeals erred in ruling that Diller Telephone had waived any objection it had to the Jantzens’ application and forfeited any right to participate in the proceedings.
V. ANALYSIS OF DILLER TELEPHONE’S SUMMARIZED ASSIGNMENTS OF ERROR
In the interest of judicial economy, we will review Diller Telephone’s summarized assignments of error rather than remanding the cause to the Court of Appeals.
1. Evidence Considered
In the first summarized assignment of error, Diller Telephone urges that in connection with the “adequacy of service” issue, the PSC erred in considering certain evidence, including the *98 testimony that those calling the son must pay toll charges. More specifically, Diller Telephone urges that § 75-613(1) precludes consideration of any toll charges in determining whether service is adequate. This is simply not so.
The statute clearly precludes the PSC from considering the applicants’ toll charges for long-distance calls they make. But there is no mention in the statute prohibiting the PSC from taking into consideration that members of an applicant’s community of interest are reluctant to call the applicant because of toll charges they would incur.
In construing a statute, a court must determine and give effect to the purpose and intent of the Legislature as ascertained from the entire language of the statute considered in its plain, ordinary, and popular sense.
Fecht
v.
The Bunnell
Co.,
The plain meaning of the statutory language allows the PSC to consider, in determining the adequacy of the service the applicants receive, the evidence that toll charges deter others in the son’s community of interest from calling him. The issue is not, as Diller Telephone asserts, that it is accountable for toll charges which persons in adjacent telephone service areas are required to pay, but, rather, that the service as operated curtails calls to the son from those in his community of interest.
In view of this determination and the conclusion which follows, we need not, and therefore do not, concern ourselves with whether the PSC properly received the other evidence before it.
*99 2. Nature of PSC’s Decision
In its second and last summarized assignment of error, Diller Telephone claims the PSC’s order is arbitrary and capricious. In this regard, Diller Telephone asserts that there is no competent evidence to support the PSC’s conclusions (a) that the son does not receive calls because of the toll charges, (b) that Diller Telephone does not provide adequate telephone service to the son’s community of interest, and (c) as to the amount of Diller Telephone’s loss of investment.
(a) Toll Charges
As noted earlier, in determining that the son receives inadequate service, the PSC relied in part on the son’s testimony that members of his community of interest do not call him because of the toll charges they would incur.
Diller Telephone urges that the evidence on this issue was purely speculative and, as such, does not support the PSC’s findings.
One difficulty with Diller Telephone’s contention is that it did not object to the son’s testimony in this regard. Whatever may be the PSC’s “relaxed rules” of evidence,
In re Application of Overland Armored Exp., 229
Neb. 524, 530,
Thus, the question is merely one of credibility of the witnesses and the weight it should be given. The credibility of witnesses and the weight to be given their testimony were for the PSC as the trier of fact. See,
Douglas Cty. Health Dept. Emp. Assn. v. Douglas Cty., 229
Neb. 301,
Where the question is one of the competency of evidence, see part II above, the issue on appeal is whether the PSC’s decision was arbitrary and capricious. Arbitrary action has been defined by this court, with reference to administrative agencies, as action taken in disregard of the facts or circumstances of the case, without some basis which would lead a reasonable and honest person to the same conclusion.
Wagner v. City of Omaha,
A capricious decision is one guided by fancy rather than by judgment or settled purpose; such a decision is apt to change suddenly; it is freakish, whimsical, humorsome. In re Application A-16642, supra.
An agency’s judgment must be based on a factual foundation and must give due consideration to all the essential elements involved.
Godden v. Department of Public Welfare,
The evidence, as detailed in part III above, is overwhelming that the son’s community of interest is in Plymouth. Despite the *101 conditional wording of the PSC’s finding that “ [i]f [members of an applicant’s community of interest] do not call because of the toll charges, then the service received by the applicant is not adequate,” the fair import of the finding is that calls to the son are hampered because of the toll charges.
(b) Adequacy of Service Provided
Diller Telephone next asserts that the PSC’s finding that adequate service is not provided to the son’s community of interest is not supported by competent evidence.
Diller Telephone argues that the PSC’s reliance on
In re Application of George Farm
Co.,
In In re Application of George Farm Co., the applicant farm corporation applied to have its property removed from Northeast Nebraska Telephone Company’s service area and placed within Northwestern Bell Telephone Company’s service area. Three residences were located on the corporation’s property, which was divided approximately in half by the boundary line separating the two telephone companies. The president of the corporation and an employee lived in houses located within one-fourth of a mile of Northwestern Bell’s boundary line, but were served by Northeast Nebraska Telephone. A trailer home on the property was served by Northwestern Bell. The corporation did virtually all of its business within Northwestern Bell’s service area, and its business and social contacts were in Northwestern Bell’s service area as well. Because the applicant subscribed to a flat-rate foreign-exchange service, it was not charged for long-distance calls made to Northwestern Bell’s service area.
Based on the corporation president’s statement that the existing telephone service was “ ‘okay,’ ”
id.
at 25,
Diller Telephone argues first that the In re Application of George Farm Co. record did not support our conclusion that the farm corporation was forced to pay for two telephone services for the same property; rather, that was a choice made by the corporation in order to avoid long-distance toll charges. It also urges that because the foreign-exchange charge was essentially a discounted monthly toll charge for long-distance calls, the PSC could not have considered the service inadequate.
However, the overriding consideration was that because the farm corporation’s property was served by two telephone companies, the corporation could obtain adequate service to its community of interest only by paying for foreign-exchange service. Yet, the corporation’s only contact with Northeast Nebraska Telephone was the fact that part of the corporation’s property fell within Northeast Nebraska Telephone’s service area. Thus, the entire record demonstrated that the denial of the corporation’s request was arbitrary and capricious.
Nonetheless, Diller Telephone argues that In re Application of George Farm Co. is not applicable to the case at hand because, whereas in In re Application of George Farm Co., a single party owned one continuous piece of property bisected by two telephone companies, here there are two pieces of property separated by a mile of ground or road.
But what makes In re Application of George Farm Co. applicable is the fact that both properties involved here are owned by the same individual, the father, and constitute but a single farm operation. Both the father and son testified to the recurring problems caused by having to deal with two telephone companies. The impact of multiple telephone service is the same whether a farm operation is conducted on one piece of land or on two nearby pieces. The important consideration is that the Jantzens can obtain adequate service to their community of interest only by having both parts of their operation serviced by one telephone company.
*103 (c) Loss of Investment
The difference between the investment loss of $338.91 found by the PSC and the $1,261.21 claimed by Diller Telephone rests on the PSC’s refusal to include in its computation the costs of physically disconnecting the Jantzens’ line, the costs Diller Telephone foresaw in keeping a record of the Jantzens’ removal from its service, and Diller Telephone’s investment in its plant.
In
Hartman
v.
Glenwood Tel. Membership Corp.,
The PSC’s computation of Diller Telephone’s investment loss as consisting of the depreciated value of the items connecting the second farm to the service provided by Diller Telephone is not arbitrary and capricious, but reasonable.
VI. JUDGMENT
For the foregoing reasons, the judgment of the Court of Appeals is affirmed but modified by the direction that it reinstate the third order of the PSC.
Affirmed as modified.
