Assume that you have a sample of n1 = 4, with the sample mean X_bar1 = 48, and a sample standard deviation of S1 = 4, and you have an independent sample of n2 = 6 from another population with a sample mean of X_bar2 = 39 and the sample standard deviation S2 = 3. Assuming the population variances are equal, at the 0.01 level of significance, is there evidence that u1 > u2?
