The height of an 8th grader is modeled using the normal distribution shown below_ The mean of the distribution is 69.1 in and the standard deviation is 2.1 in In the figure_ V is number along the axis and is under the highest part of the curve_ And, U and W are numbers along the axis that are each the same distance away from V. Use the empirical rule to choose the best value for the percentage of the area under the curve that is shaded, and find the values of U, V, and W. Percentage of total area shaded: (Choose one) U V 72 W 74 Height (in inches) U - [7 v- 0] W = U
