Do a two-sample test for equality of means assuming equal variances. Calculate the p-value. Comparison of GPA for randomly chosen college juniors and seniors: ¯ x1 = 3.05, s1 = .20, n1 = 15, ¯ x2 = 3.25, s2 = .30, n2 = 15, α = .025, left-tailed t..
Check any assumptions of the hypothesis test; Write down both the null and alternative hypotheses; Carry out the t test and report the p-value, and the test statistic.
