The height of an 8th grader is modeled using the normal distribution shown below. The mean of the distribution is 61.2 in and the standard deviation is 1.3 in.
In the figure, there are three missing values to fill in along the axis. The midde value is under the highest part of the curve. And, the left
and right values are each the same distance away from the middle value.
Use the empirical rule to choose the best value for the percentage of the area under the curve that is shaded, and nil in the missing values
along the axis.
