Question

The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of 98.18 degrees°F and a standard deviation of 0.58 degrees°F. Using the empirical rule, find each approximate percentage below. a. What is the approximate percentage of healthy adults with body temperatures within 22 standard deviationsdeviations of the mean, or between 97.02 degrees°F and 99.34 degrees°F? b. What is the approximate percentage of healthy adults with body temperatures between 97.60 degrees°F and 98.76 degrees°F?

Explanation / Answer

a) 97.02 degrees°F and 99.34 degrees°F lies 2 standard deviation away from the mean, so by empirical rule 95.5% of data will lies in this interval

b) 97.60 degrees°F and 98.76 degrees°F lies 1 standard deviation away from the mean, so by empirical rule 68.3% of data will lies in this interval
