Use the P-value hypothesis-testing method
State the hypotheses and identify the claim.
1. Ho: μ D 40 (Choose the letter of the best answer)
A. < B. > C. ≤ D. ≥ E. = F. ≠
2. Ha: μ 40 (Choose the letter of the best answer)
A. < B. > C. ≤ D. ≥ E. = F. ≠
3. The claim is (Choose the letter of the best answer)
A. Ho B. Ha
4. Type of Test: - tailed test (Choose the letter of the best answer)
A. Right B. Left C. Two
5. Compute the test value.
Test Value = (Type the exact answer)
6. Find the P-value
P-value: (Type the exact answer)
Make the decision.
7. P a (Choose the letter of the best answer)
A. ≤ B. >
8. Decision: Ho (Choose the letter of the best answer)
A. Accept (Fail to reject) B.Reject
Summarize the results.
