Question

Determine the $z$-score for which the area under the standard normal curve to its left is$0.01$.

Short answer

The z-score under the usual normal curve with the area $0.01$to the left is around$-2.33.$

Step-by-step solution

Given information

The area given area is $0.01$.

Explanation

The given area is$-0.01$

Begin by looking for the area $0.01$in the table's body. The item isn't on the table. $0.0099$is the nearest area. The matching z-score for that area is$-2.33$.

As a result, the z-score under the usual normal curve with the area $0.01$to the left is around $-2.33$, which may be depicted as
