Chapter 6, Problem 84CRE

Females’ Body Temperatures A study of human body temperatures using healthy women showed a mean of $98.4{ }^{\circ }\text{F}$ and a standard deviation of about $0.70{ }^{\circ }\text{F}$. Assume the temperatures are approximately Normally distributed.

a. Find the percentage of healthy women with temperatures below $98.6{ }^{\circ }\text{F}$ (this temperature was considered typical for many decades).

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