Two random samples of 40 students were drawn independently from two populations of students. Assume their aptitude tests are normally distributed (total points = 100). The following statistics regarding their scores in an aptitude test were obtained:xbar1 = 76 s1= 8 xbar2 = 72 and s2= 6.5. Do not assume population variances are equal. Use all formulas assuming unequal variances.Test at the 5% significance level to determine whether we can infer that the two population means differ.Explain how to use the 95% confidence interval to test the hypotheses at a = .05.

When the background music tempo was slow, the mean amount of bar purchases for a sample of 19 restaurant patrons was $30.44 with a standard deviation of $15.90. When the background music tempo was fast, the mean amount of bar purchases for a sample of 14 patrons in the same restaurant was $21.17 with a standard deviation of $9.10. Assuming equal variances, at α = 0.10, is the true mean higher when the music is slow?
