Assume that human body temperatures are normally distributed with a mean of 98.20 degrees Upper Fand a standard deviation of 0.64 degrees Upper F. a. A hospital uses 100.6 degrees Upper Fas the lowest temperature considered to be a fever. What percentage of normal and healthy persons would be considered to have a fever? Does this percentage suggest that a cutoff of 100.6 degrees Upper Fis appropriate?b. Physicians want to select a minimum temperature for requiring further medical tests. What should that temperature be, if we want only 5.0% of healthy people to exceed it? (Such a result is a false positive, meaning that the test result is positive, but the subject is not really sick.)
