For the following information, determine whether a normal sampling distribution can be used, where p is the population proportion, a is the level of significance, pis the sample proportion, and n is the sample size. If it can be used, test the claim. Claim: p>0.64; a=0.06. Sample statistics: p=0.72, n = 325 Let q=1-p and l -p and let q=1-p. A normal sampling distribution can be used here, since np 25 and nq 25. If a normal sampling distribution can be used, identify the hypotheses for testing the claim. Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. ⒸA.

If a normal sampling distribution can be used, identify the critical value(s) for this test. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. Zo= (Round to two decimal places as needed. Use a comma to separate answers as needed.) OB. A normal sampling distribution cannot be used. If a normal sampling distribution can be used, identify the rejection region(s). Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. A. The rejection region is z< (Round to two decimal places as needed.) OB. The rejection region is z> (Round to two decimal places as needed.) <2< (Round to two decimal places as needed.) TOC. The rejection region is

D. The rejection regions are z< and z> (Round to two decimal places as needed.) OE. A normal sampling distribution cannot be used. If a normal sampling distribution can be used, identify standardized test statistic z. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. Z= (Round to two decimal places as needed.) B. A normal sampling distribution cannot be used. If a normal sampling distribution can be used, decide whether to reject or fail to reject the null hypothesis and interpret the decision. Choose the correct answer below. A. Reject the null hypothesis. There is not enough evidence to support the claim. OB. Reject the null hypothesis. There is enough evidence to support the claim. c. Fail to reject the null hypothesis. There is not enough evidence to support the claim. PPVER
