According to a random sample taken at 12  A.M., body temperatures of healthy adults have a  bell-shaped distribution with a mean

of  98.17degrees°Fand a standard deviation of 0.68 degrees°F.
Using  Chebyshev's theorem, what do we know about the percentage of healthy adults with body temperatures that are within 2
standard deviations of the mean? What are the minimum and maximum possible body temperatures that are within 2
standard deviations of the mean? At least nothing % of healthy adults have body temperatures within 2 standard deviations of 98.17degrees°F.
