- Find the area under the standard normal distribution curve between =z0.45 and =z2.45. Use a TI-83 Plus/TI-84 Plus calculator and round the answer to at least four decimal places. The area between the z values isThe score on a standardized test for a certain year is modeled using the normal distribution shown below. The mean of the distribution is 56.7 points and the standard deviation is 4.8 points. 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.
