Plot- Standard Deviation vs Normal Probabilities vs Z values
Here I plotted Standard Deviations vs Z Values on x - axis (Red)
Normal Probabilities vs Z Values on x - axis (Purple)
You can Model Sigma(x) to the Red Curve by moving Sigma 1 and Mu.
Activate Functions: Click in Boxes. Look at : Mu = - 5 and Sigma = 4.69
Notice how it models the probabilities of the Normal Curve.
