Part 1
The body temperatures of a group of healthy adults have a​ bell-shaped distribution with a mean of 98.11°F and a standard deviation of 0.59°F. Using the empirical​ rule, find each approximate percentage below.
a.
What is the approximate percentage of healthy adults with body temperatures within 1 standard deviation of the​ mean, or between 97.52°F and 98.70°​F?
b.
What is the approximate percentage of healthy adults with body temperatures between 96.34°F and 99.88°​F?

Answer 1

a. Using the empirical rule, approximately 68% of healthy adults have body temperatures within 1 standard deviation of the mean, or between 97.52°F and 98.70°F.

b. Using the empirical rule, approximately 99.7% of healthy adults have body temperatures between 96.34°F and 99.88°F, which is within 3 standard deviations of the mean.
