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.) Click to view page 1 of the table. Click to view page 2 of the table. a. The percentage of normal and healthy persons considered to have a fever is %. (Round to two decimal places as needed.) Does this percentage suggest that a cutoff of 100.6°F is appropriate? OA. No, because there is a large probability that a normal and healthy person would be considered to have a fever. OB. Yes, because there is a large probability that a normal and healthy person would be considered to have a fever. OC. Yes, because there is a small probability that a normal and healthy person would be considered to have a fever. OD. 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 °F if we want only 5.0% of healthy people to exceed it. (Round to two decimal places as needed.)
