Estimate the mean body temperature of men, with a 2-SD margin of error.
Is there evidence that the mean body temperature of men differs from the mean body temperature of women?

Male
96.9
97.4
97.5
97.8
97.8
97.9
98.0
98.1
98.6
98.8

Female
97.8
98.0
98.2

98.6
98.8
98.8
99.2
99.4



First find the mean average for men. Then what appropriate bound and estimator do I use? I have something like this, (97.88-2.12) +- 2 sqrt[? ] I am alreadya bit confused. Can you please steer me in the right direction. I am unsure what formula to use. Thankyou.
