Chapter 6, Problem 41SE

Inverse Normal, Standard In a standard Normal distribution, if the area to the left of a $z$ - score is about 0.6666, what is the approximate $z$ -score?

First locate, inside the table, the number closest to 0.6666.

Then find the $z$ -score by adding 0.4 and 0.03; refer to the table. Draw a sketch of the Normal curve, showing the area and the $z$ -score.
