The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of 98.03F and a standard deviation of 0.47F. 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 96.62F and 99.44F? b. What is the approximate percentage of healthy adults with body temperatures between 97.09F and 98.97F
