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 11 F and a standard deviation 0 65 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 of healthy adults have body temperatures within 3 standard deviations of 98 11 F Round to the nearest percent as needed
