Assume that human body temperatures are normally distributed with a mean of 98.22degrees F and a standard deviation of 0.64 degrees F.

A) A hospital uses 100.6 degrees 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 F is appropriate?

B) Physicians want to select a minimum temperature for requiring further medical test. What should that temperature be, if we want only 5.0% of healthy people tp exceed it? ( Such a result is a false posivtive, meaning that the test result is positive, but the subject is not really sick.)
