= (1 point) Two independent samples have been selected, 100 observations from population 1 and 93 observations from population 2. The sample means have been calculated to be x1 = 10.1 and x2 = 9.5. From previous = experience with these populations, it is known that the variances are oỉ = 33 and oź = 31. For the hypothesis test of H. : (ui – u2) < 0 and Hq :(ui - M2) > 0 Use a = 0.03. (a) Compute the test statistic. = = - z = (b) Find the approximate p-value p – value = The final conclustion is A. There is not sufficient evidence to reject the null hypothesis that (M1 - M2) < 0. B. We can reject the null hypothesis that (ui - M2) < 0 and accept that (M1 - M2) > 0. -
