Assume that human body temperatures are normally distributed with a mean of 98.23°F and a standard deviation of 0.61°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 toexceed 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.)

Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is 68 miles per hour, with a standard deviation of 3 miles per hour. Estimate the percent of vehicles whose speeds are between 65 miles per hour and 71 miles per hour. (Assume the data set has a bell-shaped distribution.) Approximately nothing% of vehicles travel between 65 miles per hour and 71 miles per hour.
