For each of the following situations, compute the standard error of the mean (Om) and Za/2. (Please, give your answer to exactly five decimal places) 4.1 m = 72, 0 = 12.00, n = 60, a = 0.7693; Om = Za/2 = 4.2 m = 20, o = 5.56, n = 5, a = 0.2431; Za/2 = 4.3 m = 55, 0 = 47.45, n = 7, a = 0.3322; Om = Za/2 = 4.4 m = 88, 0 = 7.63, n = 30, a = 0.6903; Om = Za/2 = 4.5 m = 36, 0 = 7.12, n = 89, a = 0.3598; Za/2 =
