According to a random sample taken at 12 AM, body temperatures of healthy adults have a bell-shaped distribution with a mean of 98. 16°F and a standard deviation of 0 64°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 of healthy adults have...

A medical researcher believes that a drug changes the body's temperature. Seven test subjects are randomly selected and the body temperature of each is measured. The subjects are then given the drug, and after 30 minutes, the body temperature of each is measured again. The results are listed in the table below. Is there enough evidence to conclude that the drug changes the body's temperature? Let d = (body temperature after taking drug)-(body temperature before taking drug). Use a significance...
