According to a random sample taken at 12 A.M., body temperatures of healthy adults have a bell-shaped distribution with a mean of 98.26 F and a standard deviation of 0.59 F. Using Chebyshev's theorem, what do we know about the percentage of healthy adults with body temperatures that are within 3 standard deviations of the mean? What are the minimum and maximum possible body temperatures that are within 3 standard deviations of the mean? At least 88.8 % of healthy adults have body temperatures within 3 standard deviations of 98.26 F. (Round to the nearest percent as needed.)
