Suppose you want to test the claim that H, #H2. Two samples are randomly selected from each population. The sample statistics are given below. At a level of significance of a = 0.02, when should you reject Ho? 33 Test the claim about the difference between two population means u, and u2 at the level of significance a. Assume the samples n1 = 51, n2 = 38, X1 = 3.5, X2 = 3.9, 61 = 0.76, 62 = 0.51 are random and independent, and the populations are normally distributed. Claim: H1 S H2; a =0.05. Assume o, #62 Sample statistics: X, =2417, s, = 173, n, = 13 and *2 = 2308, $2 = 54, n2 = 10 A. Reject Ho if the standardized test statistic is less than - 2.575 or greater than 2.575. O B. Reject Ho if the standardized test statistic is less than - 1.645 or greater than 1.645. O C. Reject Ho if the standardized test statistic is less than - 1.96 or greater than 1.96. Identify the null and alternative hypotheses. Choose the correct answer below. O D. Reject Ho if the standardized test statistic is less than - 2.33 or greater than 2.33. OA. HO: My SH2 OB. HO: H1 = H2 Ha: H1 > H2 Ha: H1 # H2 O C. Ho: H1 > H2 OD. HO: H1 # H2 Ha: H1 SH2 Ha: H1 = H2 Find the critical values, to, to test the claim that , = H2. Two samples are randomly selected and come from populations that are OE. HO:My
