The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of

98.03degreesF

and a standard deviation of

0.61F.

Using the empirical rule, find each approximate percentage below.

a.	What is the approximate percentage of healthy adults with body temperatures within 2 standard deviation of the mean, or between 96.81F and 99.25F?
b.	What is the approximate percentage of healthy adults with body temperatures between 96.20sF and 99.86F?
