.0222, or 2.22%
Explanation:
If you have a graphing calculator, you can use it to find the area.
Hit 2nd > VARS > 2: normalcdf(
This will prompt you for the lower bound, upper bound, mean (
First, fill in your lower and upper bounds. You want to find the area to the right of z = 2.01, which means 2.01 and everything above that. Therefore,
lower bound = 2.01
upper bound = 999
Keep
Then press paste and enter, and you should get an answer of approximately .02221, or 2.22%.
