Assume that human body temperatures are normally distributed with a mean of

98.22F and a standard deviation of 0.62F.

a. A hospital uses 100.6F 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

100.6F 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.)

a. The percentage of normal and healthy persons considered to have a fever is

__need aswer______%. (Round to two decimal places as needed.)

Part 2

Does this percentage suggest that a cutoff of 100.6F is appropriate?

Select A B C OR D

A.

No, because there is a large probability that a normal and healthy person would be considered to have a fever.

B.Yes, because there is a small probability that a normal and healthy person would be considered to have a fever.

C.

Yes, because there is a large probability that a normal and healthy person would be considered to have a fever.

D.

No, because there is a small probability that a normal and healthy person would be considered to have a fever.

b. The minimum temperature for requiring further medical tests should be

____ NEED ANSWER___ F if we want only 5.0% of healthy people to exceed it.
