Test H0: μ1 ≤ μ2; H1: μ1 > μ2 at α = .05, when 12X'>1 = 75.4, 12X'>2 = 72.2, s1 = 3.3, s2 = 2.1, n1 = 6, n2 = 6. Determine which test you are performing; show the hypotheses, the test statistic and critical values and list whether one-tailed or two-tailed. Here mu is the Greek letter which is employed to determine population mean and Xbar is the sample mean.
