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, p is the sample proportion, and n is the sample size. If it can be used, test the claim. Claim: p20.38; a = 0.04. Sample statistics: p= 0.30, n= 160 E A. The rejection region is z< -1.75. (Round to two decimal places as needed.) O B. The rejection region is . (Round to two decimal places as needed.) O D. The rejection region is z> (Round to two decimal places as needed.) O E. Anormal sampling distribution cannot be used. If a nomal 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. VA z= -2.08 (Round to two decimal places as needed.) O 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. O A. Reject the null hypothesis. There is enough evidence to reject the claim. O B. Reject the null hypothesis. There is not enough evidence to reject the claim. O C. Fail to reject the null hypothesis. There is not enough evidence to reject the claim. O D. Fail to reject the null hypothesis. There is enough evidence to reject the claim
