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: p> 0.44; a=0.08. Sample statistics: p= 0.48, n = 225 ... 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. A. z= 1.21 (Round to two decimal places as needed.) O B. Anormal 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. Fail to reject the null hypothesis. There is enough evidence to support the claim. O B. Reject the null hypothesis. There is enough evidence to support the claim. O C. Fail to reject the null hypothesis. There is not enough evidence to support the claim. O D. Reject the null hypothesis. There is not enough evidence to support the claim. O E. Anormal sampling distribution cannot be used.
