The annual amounts of rainfall in a certain region are modeled using the normal distribution shown below. The mean of the distribution is 30.8 cm and the standard deviation is
3.3cm
. In the figure,
V
is a 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
