The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of 98.27F and a standard deviation of 0.48F. Using the empirical rule, find each appro percentage below. a. What is the approximate percentage of healthy adults with body temperatures within 3 standard deviations of the mean, or between 96.83F and 99.71F? b. What is the approximate percentage of healthy adults with body temperatures between 97.79F and 98.75F? a. Approximately % of healthy adults in this group have body temperatures within 3 standard deviations of the mean, or between 96.83F and 99.71F. (Type an integer or a decimal. Do not round.)
