Question
Suppose you want to test the claim that u, 2. Two samples are randomly selected from normal populations. The sample statistics are given below. Assume that
o =0. At a level of significance of a = 0.05, when should you reject Ho?
n= 14, n2 12, x, = 16, x, = 17, s, =2.5, s, = 2.8
O A. Reject Ho if the standardized test statistic is less than -2.492 or greater than 2.492
O B. Reject Ho if the standardized test statistic is less than -2.064 or greater than 2.064.
O C. Reject Ho if the standardized test statistic is less than - 1.318 or greater than 1.318.
O D. Reject Ho if the standardized test statistic is less than - 1.711 or greater than 1.711.
