(1 point) Test the given claim using the or = 0.05 significance level and assuming that the populations are normally distributed. Claim: The treatment population and the placebo population have different variances. Treatment group: n = 6, I = 64.6, s = 18. Placebo group: n = 11, X = 67.2, s = 13.8. The test statistic is The smaller critical value is The larger critical value is What is your conclusion? A. There is not sufficient evidence to support the claim that the treatment and placebo populations have different variances. OB.
