that lies between one and two standard deviations above the mean. (If you are not

(b) What percent of the data in the distribution is represented by the area you shaded
in?

Answer 1

Answer:

Step-by-step explanation:

This is a standard normal distribution which means it has a mean of 0 and a standard deviation of 1. To shade 1 and 2 standard deviations above the mean just color in the area under the curve between 1 and 2

The percent of data is equal to .9772-.8413= .1359= 13.59%
