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 α using the given sample statistics. Claim: p < 0.12; α-0.10; Sample statistics: p-0.08, n-25 Can the normal sampling distribution be used? O A. No, because np is less than 5. O B. Yes, because pq is greater than α = 0.10 C. No, because nq is less than 5. O D. Yes, because both np and nq are greater than or equal to 5. State the null and alternative hypotheses. Choose the correct answer below. OA. Ho:p20.12 Ha: p<0.12 O B. Ho: p 0.12 Ha: p#0.12 C. Ho: ps0.12 O D. The test cannot be performed. 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 O B. The test cannot be performed. Hap>0.12 (Round to two decimal places as needed. Use a comma to separate answers as needed.)

Answer 1

$\hat p$ = 0.08, n = 25

Normal distribution be used:

Answer A: No, because np is less than 5.

Answer for all the next 4 parts is

The test cannot be performed.
