You want to see graphically the effect of changing the standard deviation of a Normal distribution. Let μ = 100 for both distributions, but let σ = 10 for one and σ = 16 for the other distribution. Recall that for each distribution the first value should be 3σ below the mean of 100, and the last value should be 3σ above the mean of 100. When MINITAB creates the X values for you, for both distributions this time set...
