Chapter 6, Problem 87CRE

Males’ Body Temperatures A study of human body temperatures using healthy men showed a mean of $98.1{ }^{\circ }\text{F}$ and a standard deviation of $\mathrm{0.70.}{ }^{\circ }\text{F}$ Assume the temperatures are approximately normally distributed.

a. Find the percentage of healthy men with temperatures below $98.6°\text{F}$ (that temperature was considered typical for many decades).

b. What temperature does a healthy man have if his temperature is at the 76th percentile?
