Question
Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the population proportion p at the given level of significance a using the given sample statistics.
Claim: p < 0.12; a = 0.10; Sample statistics: p = 0.08, n = 25
Can the normal sampling distribution be used?
O A. Yes, because both np and nq are greater than or equal to 5.
O B. Yes, because pq is greater than a = 0.10.
O C. No, because ng is less than 5.
O D. No, because np is less than 5
State the null and alternative hypotheses. Choose the correct answer below.
O A. Ho: p20.12
Ha: p<0.12
О В. Но рs0.12
Hai p>0.12
ОС. Но Р3D0.12
Hai p+0.12
O D. The test cannot be performed.

O D. The test cannot be pertormed.
Determine the critical value(s). Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
O A. The critical value(s) is/are
(Round to two decimal places as needed. Use a comma to separate answers as needed.)
O B. The test cannot be performed.
Find the z-test statistic. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
O A.
(Round to two decimal places as needed.)
B. The test cannot be performed.
What is the result of the test?
O A. Fail to reject Ho. The data do not provide sufficient evidence to support the claim.
O B. Reject Ho. The data do not provide sufficient evidence to support the claim.
OC. Reject Ho. The data provide sufficient evidence to support the claim.
O D. Fail to reject Ho. The data provide sufficient evidence to support the claim.
O E. The test cannot be performed.
