Assume that you have a sample of n1 = 7, with the sample mean x̄1 = 45, and a sample standard deviation of Upper S1 = 5, and you have an independent sample of n2=4 from another population with a sample mean of Upper x̄2 = 38 and the sample standard deviation Upper S2 = 6. Assuming the population variances are equal, at the 0.01 level of significance, is there evidence that μ1>μ2?
