Technology. In Exercises 9–12, test the given claim by using the display provided from technology. Use a 0.05 significance level. Identify the null and alternative hypotheses, test statistic, P-value (or range of P-values), or critical value(s), and state the final conclusion that addresses the original claim.

Body Temperatures Data Set 3 “Body Temperatures” in Appendix B includes 93 body temperatures measured at 12AM on day 1 of a study, and the accompanying XLSTAT display results from using those data to test the claim that the mean body temperature is equal to 98.6°F. Conduct the hypothesis test using these results.

For Exercise 10

Step 1

**Given:**

From the data,

Null and Alternative Hypotheses:

Step 2

Step 3

This corresponds to a two-tail test, for which a t-test for one mean, with unknown population standard deviation will be used.

The number of degrees of freedom are df = n-1 = 93-1...
