04/08/22 3:06 PM Question 8, 6.2.30 HW Score: 68.89%, 6.2 of 9 points Save Homework: Section 6.2 Homework Part 1 of 3 Points: 0 of 1 Assume that human body temperatures are normally distributed with a mean of 98.22 F and a standard deviation of 0.610F. 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? (Such a result is a false positive, meaning that the test result is positive, but the subject is not really sick.)
