Question
The minimum temperature for requiring further medical test should be _F if we want only 5.0% of health people to exceed it.
Assume that human body temperatures are normally distributed with a mean of 98.23°F and a standard deviation of 0.61F a. A hospital uses 100.6°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"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?
