According to a random sample taken at 12 a. m., body temperatures of healthy adults have a bell-shaped distribution with a mean of 98.28degreesf and a standard deviation of 0.63degreesf. 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 98.28degreesf.
