Jovon conducts a hypothesis test for a population mean difference. The null and alternative hypotheses are as follows: Ho: µ1 ≤ µ2; Ha: µ1 > µ2. His t-test statistic = 2.85 with df = 19.

What is the p-value associated with his hypothesis test using Table A.5 or TI function?

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. A study was done on body temperatures of men and women. Here are the sample statistics for the men: x1 = 97.55oF, s1 = 0.83oF, n1 = 11, and for the women: x2 = 97.31oF, s2 = 0.65oF, n2 = 59. Use a 0.06 significance level to test the claim that µ1 > µ2.
