This is a consolidated appeal by seven defendants convicted of assorted drug offenses. They contend, inter alia, that (1) the district court lacked subject matter jurisdiction over their case, (2) the prosecutor’s use of peremptory challenges was discriminatory, and (3) the prosecutor deprived them of a fair trial by making improper comments during his closing argument. We affirm each of the challenged convictions and sentences.
I. Background
On the Menominee Reservation near Green Bay, Wisconsin, drug trafficking was a family affair. All seven of the defendants whose appeals were consolidated in this case are members of the same family. Patricia M. Brisk (“Brisk”), Isabel M. Cloud (“Cloud”), Leona Sanapaw (“Sa-napaw”), and Barbara Wheeloek (“Wheel-ock”) are sisters. James B. Brisk, Jr. (“Brisk, Jr.”), and Lucy A. Beauprey (“Beauprey”) are Brisk’s children. Mary Jane Denny (“Denny”) is Brisk’s niece.
On October 24, 1995, a grand jury for the Eastern District of Wisconsin returned an indictment charging the appellants, as well as several others, with numerous drug-related offenses. In an unrelated cáse, on April 26, 1996, the government filed a sealed juvenile information against Brisk, Jr., charging him with engaging in a sexual act with a person incapable of declining participation, in violation of 18 U.S.C. §§ 2,1153, 2242(2)(B).
Pursuant to separate plea agreements, Beauprey, Brisk, and Brisk Jr. each pled guilty to one count of conspiracy to distribute and possession with intent to distribute cocaine, and one count of conspiracy to distribute and possession with intent to distribute marijuana, both in violation of 21 U.S.C. §§ 841(a)(1), 846, and 18 U.S.C. § 2. Brisk, Jr. also pled guilty to the charge in the juvenile information.
The remaining appellants elected to proceed to trial before a jury. During jury selection, which began on October 28,1996, the government exercised four of its six peremptory challenges to remove women from a venire that consisted of eighteen women and thirteen men. Several defendants objected that the government’s use of peremptories was discrhninatory. However, the judge did not rule on the issue until after the trial was over.
At trial, several witnesses testified to numerous drug transactions that involved the appellants. The evidence showed that cocaine was purchased in Milwaukee, Chicago, and northern Illinois and brought to the reservation. It was then packaged at the homes of various defendants. During his closing argument, the prosecutor asserted that drugs had been packaged in front of the young children of some of the defendants. The defendants objected that there was no evidence that the children had been present. The district judge instructed the jury to rely on its own recollection of the evidence and to disregard any comments that weren’t supported by the evidence.
On November 6, 1996, a jury found that Cloud, Denny, Sanapaw, and Wheeloek were each guilty of one count of conspiracy to distribute and possession with intent to distribute cocaine, in violation of 21 U.S.C. §§ 841(a)(1), 846, and 18 U.S.C. § 2. In addition, the jury found that Wheeloek was guilty of five counts of knowingly and intentionally distributing cocaine, in violation of 21 U.S.C. § 841(a)(1), and 18 U.S.C. § 2. Appellants’ sentences are reflected in the following chart:
Term of Supervised Appellant Imprisonment Release
Beauprey 84 mo. 4 yr.
Brisk 115 mo. 3 yr.
Brisk, Jr. 112 mo. 3 yr.
Cloud 97 mo. 4 yr.
Denny 78 mo. 4 yr.
Sanapaw 97 mo. 4 yr.
Wheeloek 125 mo. 8 yr.

Appellants raise three principal issues on appeal. First, Cloud, Denny, Sanapaw, and Wheelock argue that the district court lacked subject matter jurisdiction over their cases. Second, Denny and Wheelock argue that the government violated
Batson v. Kentucky,
II. Discussion
A. Subject Matter Jurisdiction
Cloud, Denny, Sanapaw, and Wheelock claim that the lower court lacked subject matter jurisdiction over their cases. They argue that neither the Federal Enclave Act, 18 U.S.C. § 1152, nor the Major Crimes Act, 18 U.S.C. § 1153, gave the- court jurisdiction, and that these two statutes are the only sources of federal jurisdiction over crimes committed in Indian country. We review the district court’s determination of subject matter jurisdiction de novo.
The Federal Enclave Act extends federal enclave laws, i.e., “laws where the situs of the offense is an element of the crime,”
United States v. Begay,
Taken together, the Enclave Act and the Major Crimes Act create a two-
*520
part inquiry for determining whether a federal court has subject matter jurisdiction over an enclave law case: first, the court must decide whether the case falls within the intra-Indian exception; and second, if it does, the court must decide whether the Major Crimes Act operates to take the case back out of the exception. See Negonsott v. Samuels,
We agree that neither statute provides jurisdiction, but for a different reason-the Enclave Act and the Major Crimes Act are inapposite. Both statutes deal exclusively with federal enclave laws, but enclave laws are not at issue in this case. Every circuit to consider the issue has held that the Enclave Act and Major Crimes Act do not control subject matter jurisdiction in non-enclave law cases. See, e.g., United States v. Yannott,
We begin with the general proposition that "statutes written in terms applying to all persons include members of Indian tribes as well." United States v. Funmaker,
Appellants contend that Menominee rights under the Wolf River Treaty of 1854, 10 Stat. 1064, are in jeopardy. They argue that the treaty’s promise to the Menominee of a reservation “for a home, to be held as Indian lands are held,” art. 2,
Nor do we believe that federal drug laws impermissibly impinge on Menominee lights essential to self-governance of intramural matters. While it is well established that Indians have a right to self-government that “includes the right to prescribe laws applicable to tribe members and to enforce those laws by criminal sanctions,”
Wheeler,
As a final matter, we must address the apparent conflict between this opinion and
United States v. Quiver,
in which the Supreme Court held that a federal court did not have jurisdiction over an adultery prosecution that was brought under a statute of general applicability.
B. Jury Selection
We next consider Denny and Wheeloek’s contention that the government violated
Batson v. Kentucky,
Batson
set forth a three step method for determining whether a party has exercised a peremptory challenge dis-criminatorily. First, the party alleging a violation must make a prima facie showing of intentional discrimination. Second, once this showing has been made, the burden shifts to the party that exercised the challenge to articulate a gender-neutral explanation for the challenge. Finally, the trial judge must decide whether the reasons offered are pretextual and whether the party alleging a violation has met its burden of proving purposeful discrimination.
See Batson,
We have recently held that "[u]n-like the ultimate issue of discriminatory intent, which as a factual question is enti-tied to deferential review, the preliminary question of whether a prima fa~ie case has been shown presents a mixed question of law and fact which the appellate courts should review de novo." Mahaffey v. Page,
To establish a prima fade case of gender discrimination in the exercise of a peremptory challenge, Denny and Wheelock needed to show that the government struck a member of a constitutionally protected class, and that all the relevant circumstances raised an inference of intentional discrimination. See United States v. Cooper,
Denny and Wheelock urge that the government's use of four of its six peremptory challenges to remove women from the venire constituted a pattern of strikes against women. We disagree. In McCain v. Gramley, we held that a pattern of strikes can be demonstrated "by the manner in which a party uses its strikes as compared to its total strikes or to the total number of members of the ... [protected] group."
On another note, Denny and Wheelock contend that the district court abused its discretion by failing to rule on their Batson challenge until the trial was over. They argue that by doing so, the court put off the decision until a point in the proceedings when the only remedy would have been to retry the entire case. Because Denny and Wheelock did not establish a prima facie Batsom violation, the issue is moot. However, we feel compelled to note that although Batson did not "formulate particular procedures to be followed upon a defendant's timely objection to a prosecutor's challenges," Batson,
*524 C. Closing Argument
The last of the three principal arguments on appeal concerns the prosecutor’s comments during his closing argument. Cloud, Denny, Sanapaw, and Wheelock contend that several of the prosecutor’s statements were improper and prejudicial and, thei’efore, deprived them of a fair trial in violation of their due process rights. We review the district judge’s refusal to grant a mistrial for abuse of discretion. As we have said before, “[h]aving watched the jury as they listened to the testimony, having listened to the testimony and the arguments himself, having his finger as it were on the pulse of the trial ... the district judge was in a better position than we to weigh the imponderables involved in a judgment of prejudice.”
United States v.
Williams,
To decide whether a prosecutor’s comments have deprived a defendant of a fair trial, “we first look at the disputed remarks in isolation to determine if they are proper.”
United States v. Cotnam,
In determining whether improper remarks are prejudicial enough to deprive a defendant of a fair trial, we consider the following five factors: “1) the nature and seriousness of the prosecutorial misconduct, 2) whether the prosecutor’s statements were invited by impermissible conduct by defense counsel, 3) whether the trial court instructed the jury to disregard the statements, 4) whether the defense was able to counter the improper statements through rebuttal, and 5) the weight of the evidence against the defendant.”
Cotnam,
D. Additional Issues
The remaining issues can be quickly disposed of. To begin with, Sana-paw claims that the district judge abused his discretion by allowing witnesses to testify about drug activity that predated the 1994-1995 drug conspiracy. Sanapaw contends that the testimony was irrelevant and, therefore, inadmissable under Federal Rule of Evidence 402. Fed.R.Evid. 402 (“Evidence which is not relevant is not admissible.”). Alternatively, she argues that even if the evidence was relevant, it was inadmissible under Federal Rule of Evidence 403 because it was unfairly prejudicial. 8
Neither of these arguments is persuasive. Federal Rule of Evidence 401 defines “relevant evidence” as “evidence having any tendency to make the existence of any fact that is of consequence to the determination of the action more probable or less probable than it would be without the evidence.” Fed.R.Evid. 401. This is not a difficult standard to meet. Thus, we cannot say that the district judge abused his discretion in finding that the evidence of past drug activity, often involving co-conspirators, tended to make the existence of
some
fact of consequence (such as knowledge of how to sell drugs or acquaintance with co-conspirators) more likely. Furthermore, we agree with the district judge that the testimony was not barred by Rule 403, which states that “[although relevant, evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice [or] confusion of the issues.... ” Fed.R.Evid. 403. In this case, the danger of unfair prejudice was minimal because the testimony at issue was insignificant in comparison to the overwhelming evidence against Sanapaw.
See United States v. Molinaro,
Sanapaw next argues that there was insufficient evidence to support her conviction. In particular, she contends that the government failed to prove beyond a reasonable doubt that a “participatory link” existed between her and the conspiracy. In making this sufficiency challenge, Sanapaw “faces a nearly insurmountable hurdle ... [in that] we consider the evidence in the light most favorable to the Government, defer to the credibility determination of the jury, and overturn a verdict only when the record contains no
*526
evidence, regardless of how it is weighed, from which the jury could find guilt beyond a reasonable doubt.”
United States v. Moore,
To establish a participatory link, the prosecutor was required to show that “the defendant knew of the conspiracy and that [s]he intended to join and associate h[er]self with its criminal design and purpose.”
United States v. Jean,
Sanapaw’s last argument concerns her sentence. Specifically, she contends that the district judge erred in finding her responsible for 4 kilograms of cocaine because the evidence shows only that she was responsible for 2.87 kilograms. At stake is a two level reduction in Sanapaw’s base offense level (from 30 to 28). U.S.S.G. § 2D1.1(a)(3), & (c)(5),(6). We review a judge’s attribution of drugs for clear error.
During the sentencing phase of a trial, the government has the burden of proving the amount of drugs attributable to a defendant by a preponderance of the evidence.
United States v. Rosa,
The final issue on appeal also relates to sentencing. Cloud claims that the district judge erred in refusing to grant her a two level reduction, under U.S.S.G. § 3B1.2(b), for her minor participation in the conspiracy. Such a reduction is meant for a person “who is less culpable than most other participants.” U.S.S.G. § 3B1.2, Application Note 3. It was Cloud’s burden to show by a preponderance of the evidence that she was entitled to the reduction.
United States v. Soto,
In support of her argument, Cloud points out that she did not procure drugs for the conspiracy, went along on only one drug run, and sold drugs less frequently than other co-conspirators. Her principal role in the conspiracy consisted of preparing the bindles in which the cocaine was packaged. Thus, she concludes that she was less culpable than most other participants in the conspiracy and was entitled to an offense level reduction. Cloud’s argu
*527
ment is unpersuasive because, as we have previously explained, “the fact that one plays a much lesser role than another does not mean that one is a minor participant.”
United States v. Kerr,
E. Anders Briefs and Pro Se Motions
We come at last to the Anders Briefs submitted by the attorneys for Beauprey, Brisk, and Brisk, Jr. Each brief argues that there are no non-frivolous grounds for appeal and seeks permission for the attorney to withdraw. Since all the Anders briefs are sufficient on their face, we consider only those issues raised in the briefs and the responses to the briefs. United States v. Wagner, 103 F.3d 551, 553 (7th Cir.1996). Having carefully reviewed all the materials submitted, we agree with the attorneys that there are no non-frivolous grounds for appeal as to Beauprey, Brisk, and Brisk, Jr. However, as is our practice, we decline to consider the ineffective assistance of counsel claims on direct appeal since determination of such claims requires evidence that is outside the trial record. United States v. Brooks, 125 F.3d 484, 495 (7th Cir.1997).
All that remains are the pro se motions of Brisk and Brisk, Jr. Brisk requests that she be appointed new counsel to represent her on appeal. Since we have determined that an appeal would be frivolous, she is not entitled to new counsel. For the same reason, Brisk, Jr.’s request for a copy of the full record is also unwarranted.
CONCLUSION
For the foregoing reasons, we Affirm the district court’s judgment in all respects. We also Grant the motions of the attorneys for Beauprey, Brisk, and Brisk, Jr. to withdraw, and Deny Brisk’s motion for new appointed counsel and Brisk Jr.’s request for a copy of the full record.
Notes
. The full text of the Enclave Act is as follows: Except as otherwise expressly provided by law, the general laws of the United States as to the punishment of offenses committed in any place within the sole and exclusive jurisdiction of the United States, except the District of Columbia, shall extend to the Indian country.
This section shall not extend to offenses committed by one Indian against the person or property of another Indian, nor to an}' Indian committing any offense in the Indian country'who has been punished by the local law of the tribe, or to any case where, by treaty stipulations, the exclusive jurisdiction over such offenses is or may be secured to the Indian tribes respectively.
18 U.S.C. § 1152.
. The Major Crimes Act provides that:
Any Indian who commiLs against the person or property of another Indian or other person any of tire following offenses, namely, murder, manslaughter, kidnaping, maiming, a felony under chapter 109A [sexual abuse], incest, assault with intent to commit murder, assault with a dangerous weapon, assault resulting in serious bodily injury (as defined in section 1365 of this title), an assault against an individual who has not attained the age of 16 years, arson, burglary, robbery, and a felony under section 661 of this title [embezzlement and theft] within the Indian country, shall be subject Lo the same law and penalties as all other persons committing any of the above offenses, within the exclusive jurisdiction of the United Slates. 18 U.S.C. § 1153(a).
. The distinction between enclave laws and federal laws of nationwide applicability is based on the notion that enclave laws "define traditional state law crimes and then apply them to federal enclaves by making the situs of the crime one of its elements." Gar-nett, 72 N.D.L.Rev. at 445. Thus, while enclave laws are conceived to fill traditionally state law roles, generally applicable federal laws implicate national interests. As the Ninth Circuit reasoned in United States v. Burns, "[j]ust as state law is not to apply on Indian lands, unless expressly authorized by federal statute, so also, federal enclave law is not to apply unless expressly authorized."
. While our holding in
United States v. Smith
indicated that federal jurisdiction in that case rested on the existence of a peculiarly federal crime,
.
See, e.g., Funmaker,
. A similar argument can be made about the Court's statement in a footnote of
Antelope
that "[e]xcept for the offenses enumerated in the Major Crimes Act, all crimes committed by enrolled Indians against other Indians within Indian country are subject to the jurisdiction of tribal courts.”
. On appeal, Sanapaw has not raised Federal Rule of Evidence 404(b), which states that ''[e]vidence of other crimes, wrongs, or acts is not admissible to prove the character of a person in order to show action in conformity therewith.” Fed.R.Evid. 404(b). Therefore, any arguments relying on this rule have been waived.
