The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of 98.23 F and a standard deviation of 0.44F. Using the empirical rule, find each approximate percentage below. a. What is the approximate percentage of healthy adults with body temperatures within 3 standard deviations of the mean, or between 96.91 F and 99.55 F? b. What is the approximate percentage of healthy adults with body temperatures between 97.35 F and 99.11 F? a. Approximately % of healthy adults in this group have body temperatures within 3 standard deviations of the mean, or between 96.91 F and 99.55 F. (Type an integer or a decimal. Do not round.)
