Area under the Standard Normal Curve

Question

Directions: Find the area under the standard normal curve to the left of the given z-value.

z=1.78

Answer 1

You have to know how to read a z score table for this. Looking up 1.78 on the table, the area to the left is straight off the table. It is 0.9625

If you wanted the area to the right of a z score, you have to subtract the number on the table from 1.
