Assume that human body temperatures are normally distributed with a mean of 98.19°F and a standard deviation of 0.63°F. 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.) A. What is the percentage of normal and healthy persons considered to have a fever? _______% A2. Does this percentage suggest that a cutoff of 100.6F is appropriate? A. Yes, because there is a small probability that a normal and healthy person would be considered to have a fever B.No, 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 large probability that a normal and healthy person would be considered to have a fever

Question

Assume that human body temperatures are normally distributed with a mean of 98.19°F and a standard deviation of 0.63°F.

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.)

A. What is the percentage of normal and healthy persons considered to have a fever? _______%

A2. Does this percentage suggest that a cutoff of 100.6F is appropriate?

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

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

B. What should that temperature be if we want only 5.0% of healthy people to exceed it?
