Dynamic functions
Watch the graph , check boxes if you like
You can change the standard deviation too; STD=.3 or Type in any Z values into Sigma box ; 1/Z to convert to Standard Deviations
p(x) is the normal curve Blue
L(x) is the Normal Curves own standard deviation in its tails, Green Curves
P(x) is the Standard deviation equated to the Normal Curve which was then solved for " p - normal " Green Square Curve
