Question

How do you find `z` so that 82% of the standard normal curve lies to the right of `z`?

Answer 1

`z=-1.41`

Explanation:

The area under the Standard Normal Curve is `=1`

One half of the curve represents `0.5 or 50%` area

The area lies to the right of `z` value is `=82% or 0.82`

Refer the Diagram.

The Total area can be divided as `0.42+0.5`
Refer the table for the nearest value `0.42`

It is `z` value. It is `-1.41`
