Question:
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 z-score.
