Can anyone explain and show how to use Percentage points of the normal distribution??

If you can give me some examples of using Percentage points of the normal distribution, i would really appreiciate it.

Thank you.

Here is percentage points of the normal distribution.

PERCENTAGE POINTS OF THE NORMAL DISTRIBUTION

The values z in the table are those which a random variable Z ∼ N(0, 1) exceeds with probability p;

that is, P(Z > z) = 1 − Φ(z) = p.

p z p z

0.5000 0.0000 0.0500 1.6449

0.4000 0.2533 0.0250 1.9600

0.3000 0.5244 0.0100 2.3263

0.2000 0.8416 0.0050 2.5758
