The body temperatures of a random sample of U.S. adults were taken and the results are summarized in the table below. In this problem we will use a 0.01 significance level to test the claim that men and women have different body temperatures.

1. What hypotheses should be used? Give them in both symbols and words.
2. What value of ? should be used?
3. Is it mathematically appropriate to use the methods described in this chapter to answer this question? Are the necessary conditions met? Explain, being as specific as possible. (Whether or not you think the conditions are met, do the rest of this problem.)
4. Generate a P-value, and tell meexactly what technology and function(s) you are using. Be as specific as you can.
5. State your conclusion in the context of this problem.
