1. Standard Normal Probabilities
Find the probability P(z ≤ z0).
Click Insert Function (fx)
Select Statistical as your function category
Choose NORM.S.DIST 1 2

2. Standard Normal Probabilities
You must enter Z = The value of the standard normal distribution for which you would like the cumulative probability P(z ≤ z0).
Cumulative = True if you want P(x ≤ X).
= False if you want the height of the curve at x. Use if you would like to graph the
function (not used much in this class).
Example: P(z ≤ 1.83) = .9664

3. Standard Normal Probabilities
Find the z-value giving you probability P(z ≤ z0) = P0.
Click Insert Function (fx)
Select Statistical as your function category
Choose NORM.S.INV 1 2

4. Standard Normal Probabilities
You must enter Probability = The probability P0 for which you would like the value of the standard normal distribution giving you P(z ≤ z0) = P0.
Example: Fill in the blank: P(z ≤ ____) = .90
The answer is 1.282
