Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the difference between two population proportions p, and p, at the given level of significance a using the given sample statistics. Assume the sample statistics are from independent random samples. P1 =P2, a = 0.10 x, = 108, n, = 128 and x, = 32, n, = 195 Claim: Sample statistics: Ha: P1 F P2 O E. A normal sampling distribution cannot be used, so the claim cannot be tested. Find the critical values. Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. O A. The critical values are -z, = 1.28 and zo = 1.28 (Round to two decimal places as needed.) O B. A normal sampling distribution cannot be used, so the claim cannot be tested. Find the standardized test statistic. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. (Round to two decimal places as needed.) z= O B. A normal sampling distribution cannot be used, so the claim cannot be tested. State the conclusion. Choose the correct answer below. O A. Fail to reject Ho. There is sufficient evidence that there is a difference between p, and p, O B. Reject Ho. There is sufficient evidence that there is a difference between P, and p2. OC. Fail to reject Ho. There insufficient evidence that there is a difference between p, and p2 O D. Reject Ho. There is insufficient evidence that there is a difference between p, and p2. O E. A normal sampling distribution cannot be used, so the claim cannot be tested.
