Assume that human body temperatures are normally distributed with a mean of 98.22 degrees Upper F

98.22F and a standard deviation of 0.63 degrees Upper F

0.63F.

a. A hospital uses 100.6 degrees Upper F

100.6F as the lowest temperature considered to be a fever. What percentage of normal and healthy persons would be considered to have afever? Does this percentage suggest that a cutoff of 100.6 degrees Upper F

100.6F isappropriate?

b. Physicians want to select a minimum temperature for requiring further medical tests. What should that temperaturebe, if we want only5.0% of healthy people to exceedit? (Such a result is a falsepositive, meaning that the test result ispositive, but the subject is not reallysick.)
