Question

A large random sample was taken of body temperatures of women at a university. The data from the sample were normally distributed with a mean body temperature of
98.52°F and a standard deviation of 0.727°F. Based on this sample, which percentage is the best estimate of the proportion of all women at this university who have a body
temperature more than 2 standard deviations above the mean?

Answer 1

About 2.5% of the women have a body temperature more than 2 standard deviations above the mean.

What is the empirical rule?

Empirical rule states that for a normal distribution, about 68% of the values fall within one standard deviation from the mean, 95% of the values fall within two standard deviation from the mean and 99.7% of the values fall within three standard deviation from the mean.

Amount that have more than 2 standard deviations above the mean = (100% - 95%) / 2 = 2.5%

About 2.5% of the women have a body temperature more than 2 standard deviations above the mean.
