A physician claims that joggers’ maximal volume oxygen uptake is greater than the average of all adults. A sample of 15 joggers has a mean of 40.6 milliliters per kilogram (ml/kg) and a standard deviation of 6 ml/kg. If the average of all adults is 36.7 ml/kg, is there enough evidence to support the physician’s claim at a = 0.05? Use the Traditonal Method of hypothesis testing. State the hypotheses and identify the claim. 1. Ho: μ C 36.7 (Choose the letter of the best answer) A. < B. > C. ≤ D. ≥ E. = F. ≠ 2.

Use the Traditonal Method of hypothesis testing.
State the hypotheses and identify the claim.
1. Ho: μ C 36.7 (Choose the letter of the best answer)
A. < B. > C. ≤ D. ≥ E. = F. ≠
2. Ha: μ 36.7 (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
Find the critical value(s)
4. C.V. = (Type the exact answer)
Compute the test value.
5. Sample Mean: (Type the exact answer)
6. Sample Standard Deviation: (Type the exact answer)
7. Test Value: (round answer to the nearest hundreth)
Make the decision.
8. Decision: Ho (Choose the letter of the best answer)
A. Accept (Fail to reject) B.Reject
Summarize the results.
Conclusion: There is (9) evidence to (10) the claim that the the average salary of substitute teachers in school districts in Allegheny County, Pennsylvania, is less than $60 per day. (Type the exact answer)
