Answer #1

Steps to follow while using Minitab Express

Open Menu

Graph>Probability Distribution Plots>View probabilty

New box with two options appear

(a)Distribution>Normal

Mean =0.0

Standard deviation = 1.0

(b)Shaded Area>right tailed

x-value = 2

Given Graph showing distribution appears in result, where propotion above z=2 is 2.275%

You can cross check this value using Excel formula =1-NORM.S.DIST(2,TRUE)
