Study was done on body temperatures of men and women The res

Study was done on body temperatures of men and women. The results are in the table. Assume that the two samples are independent simple random samples selected from normally distributed populations and do not assume that the population standard deviations are equal.

Mean for men is 1 Mean for women is 2

n for men is 11 n for women is 59

X bar for men is 97.52 degrees F X bar for women is 97.33 degrees F

S for men is 0.77 degrees F S for women is 0.73 degrees farenheit

A. Use a 0.01 signifcance level and test the claim that men have a higher mean than women in body temp. what are the null and alternative hypotheses?

B. The test statistic is? round to two decimal places.

C. The P-value is? round to three decimal places.

D. State conclusion for the test.

E. Construct a confidence level
