10. Human Body Temperature Data Set 2 in Appendix B includes a sample of 106 body temperatures with a mean of 98.20°F. Assume that s is known to be 0.62°F. Consider a hypothesis test that uses a 0.05 significance level to test the claim that the mean body temperature of the population is less than 98.6°F.

a. What is the test statistic?

b. What is the critical value?

c. What is the P-value?

d. What is the conclusion about the null hypothesis (reject, fail to reject)?

e. What is the final conclusion in simple nontechnical terms?
