Find the mean and standard​ deviation, and verify that the pulse rates have a distribution that is roughly normal.

Explain why the pulse rates have a distribution that is roughly normal. Choose the correct answer below.

A.

The pulse rates have a distribution that is normal because none of the data points are greater than 2 standard deviations from the mean.

B.

The pulse rates have a distribution that is normal because the mean of the data set is equal to the median of the data set.

C.

The pulse rates have a distribution that is normal because none of the data points are negative.

D.

The pulse rates have a distribution that is normal because a histogram of the data set is​ bell-shaped and symmetric.
