The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of 98.39degreesf and a standard deviation of 0.48degreesf. using the empirical rule, find each approximate percentage below. a. what is the approximate percentage of healthy adults with body temperatures within 2 standard deviations of the mean, or between 97.43degreesf and 99.35degreesf? b. what is the approximate percentage of healthy adults with body temperatures between 97.91degreesf and 98.87degreesf?

a) 95%

b) 68%

Explanation:

Here the distribution given to us is:

a) 97.43 can be written as 98.39 - 2\times 0.48 that is 2 standard deviation.

According to empirical rule, 95% of the observations lies within 2 standard deviations of the mean.

Therefore 95% is the correct answer here.

b) 97.91 can be written as: 98.39 - 1*0.53 that is 1 standard deviations less than the mean

Also, 98.87 = 98.39 + 0.48 that is 1 standard deviations above the mean.

According to the empirical rule, 68%  of the observations lies within 1 standard deviation of the mean.

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
