Work Step by Step

To find the z score given the area, we have to find the area under the curve to the left of the z score. Since we are given the area above the z score, we can subtract the given area from 100% of the area. This gives us .9761. We must then refer to table e in the back of the book. Locating the value nearest .9761, we can find that our z score is roughly 1.98.
