5. An hypothesis test is of the form Ho : µ1 – µ2 = 0 vs Ha : µi – µ2 < 0. Both populations are assumed normal with equal variance and samples are assumed independent. We draw 21 observations for the first sample and 37 observations for the second sample. State the distribution of the test statistic for this test.
