Question

The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of 98 25°F and a standard deviation of 0.68°F. Using the empirical rule, find each approximate percentage below.a. What is the approximate percentage of healthy adults with body temperatures within 1 standard deviation of the mean, or between 97.57°F and 98.93°F?

Answer 1

Given:

mean of 98 25°F and a standard deviation of 0.68°F.

Required:

Percentage of healthy adults with body temperatures within 1 standard deviation of the mean, or between 97.57°F and 98.93°

Explanation:

mean=98.25

98.93-98.25=0.68

97.57-98.25=-0.68

So 97.57°F and 98.93°F are 0.68 standard deviation from the mean 98.25F

By empirical rule we know that 68 % of the data lies within 0.68 standard deviation

of the mean

Required answer:
