The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of 98.11°F and a standard deviation of 0.69°F. Using the empirical rule, find each approximate percentage below.
a. What is the approximate percentage of healthy adults with body temperatures within 2 standard deviations of the mean, or between 96.73°F and 99.49°F?
b. What is the approximate percentage of healthy adults with body temperatures between 96.04°F and 100.18°F?
a. Approximately % of healthy adults in this group have body temperatures within 2 standard deviations of the mean, or between 96.73°F and 99.49°F.
(Type an integer or a decimal. Do not round.)
