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> 0.67; a = 0.06. Sample statistics: p = 0.72, n = 325 (Kouna to two decimar piaces as needea.) O D. The rejection region is z>. (Round to two decimal places as needed.) O E. 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. O A. z= (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. Fail to reject the null hypothesis. There is not enough evidence to support the claim. O B. Reject the null hypothesis. There is not enough evidence to support the claim. of OC. Reject the null hypothesis. There is ugh evidence to support the claim. O D. Fail to reject the null hypothesis. There is enough evidence to support the claim. 2 of O E. A normal sampling distribution cannot be used.

Transcribed Image Text: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>0.67; a = 0.06. Sample statistics: p=0.72, n= 325
(Rounu to two decimai piaces as needed.)
O D. The rejection region is z>
(Round to two decimal places as needed.)
O E. 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.
O A. z=
(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.
