The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of 98.31F and a standard deviation of 0.43F. 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 97.88F and 98.74F?

b) What is the approximate percentage of healthy adults with body temperatures between 97.02F and 99.60F?

a) approximately ________ % of healthy adults in this group have body temperatures within 1 standard

deviation of the mean, or between 97.88F and 98.74F. (type an integer or a decimal. do not round)

b) approximately ________ % of healthy adults in this group have body temperatures between

97.02F and 99.60F. (type an integer or a decimal. do not round)
