The annual rainfall in a certain region is modeled using the normal distribution shown below. The mean of the distribution is 36.9 cm and the standard deviation is 4.8 cm.
In the figure, V is a number along the axis and is under the highest part of the curve.
And, U and Ware 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.
