Question

According to a random sample taken at 12 AM, body temperatures of healthy adults have a bell-shaped distribution with a mean of 98.16°F and a standard deviation of 0.64°F Using Chebyshev's theorem, what do we know about the percentage of healthy adults with body temperatures that are within 2 standard deviations of the mean? What are the minimum and maximum possible body temperatures that are within 2 standard deviations of the mean? 

At least _______  of healthy adults have body temperatures within 2 standard deviations of 98.16°F 

(Round to the nearest percent as needed.) 

The minimum possible body temperature that is within 2 standard deviations of the mean is _______ °F 

(Round to two decimal places as needed) 

The maximum possible body temperature that is within 2 standard deviations of the mean is _______ °F 

(Round to two decimal places as needed)

Answer 1

First the Chebshev's theorem is stated. The minimum and the maximum value within 2 S.D of the mean is calculated using the formula mentioned
