Assume that human body temperatures are normally distributed with a mean of 98.20 degrees Upper F and a standard deviation of 0.64 degrees Upper F
.
a. A hospital uses 100.6 degrees Upper F

as 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 F

is​ 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.)
