cs The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of 98.38 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 97.79 F and 98.97F? b. What is the approximate percentage of healthy adults with body temperatures between 96.61 F and 100. 15 F? a. Approximately |% of healthy adults in this group have body temperatures within 1 standard deviation of the mean, or between 97.79 F and 98.97 F. (Type an integer or a decimal: Do not round.)
