1 Point Two Independent Samples Have Been Selected 68 Observations From Population 1 And 59 Observations From Populat 1 (60.52 KiB) Viewed 26 times

(1 point) Two independent samples have been selected, 68 observations from population 1 and 59 observations from population 2. The sample means have been calculated to be žu = 12.8 and T2 = 7.2. From previous experience with these populations, it is known that the variances are o = 21 and ož= 30. = = (a) Determine the rejection region for the test of H: (M1 - H2) = 3.53 H: (Mu - H2) > 3.53 - using a = 0.03. 2> (b) Compute the test statistic. Z 1.20 The final conclusion is O A. We can reject Ho. OB. There is not sufficient evidence to reject H. (c) Construct a 97 % confidence interval for (u1 - H2). -4.518 <(u1 - H2) < 15.718
