This question: 4 point(s) possible Suppose you want to test the claim that u, = 12 . Two samples are randomly selected from normal populations. The sample statistics are given below. Assume that , =62. At a level of significance of a = 0.05, when should you reject Ho? n1 = 14, n2 = 12, x, =9, X2 = 10, 51 = 2.5, $2 = 2.8 A. Reject Ho if the standardized test statistic is less than - 1 711 or greater than 1 711. O B. Reject Ho if the standardized test statistic is less than - 2.492 or greater than 2 492
