Use the Standard Normal Table or technology to find the z-score that corresponds to the following cumulative area, 0.9696
The cumulative area corresponds to the z-score of ____?
Solution:
We have to find z value for the cumulative area, 0.9696.
That is find z value such that:
P( Z < z ) =0.9696
Look in z table for Area = 0.9696 or its closest area and find corresponding z value.
Area 0.9693 is closest to 0.9696 and it corresponds to 1.8 and 0.07
thus z = 1.87
Thus
The cumulative area corresponds to the z-score of 1.87
