Normal Probabilities using only The RV Sigma Equation : Set Sigma at 1 = .3413 I can now obtain all the Normal Probabilities by using my equation: I can; 1) Obtain Normal Probabilities from RV sigma equation 2) Obtain Z values 3) Always have the area of the Standard Deviation of the Normal Curve. I can obtain other intervals by changing my limits of integration. Type in Sigma values to obtain Probabilities
