The Normal Curve Challenge Solve for " P "

The Normal Curve Challenge ( Type Z Values in like this: 1/Z ) into the sigma input box to convert to standard deviations. I have provided all the relationships between:( std. ; Z ; CI ; std.=1/Z) The two equation Challenge : Equate the two Red equations together and solve for " P "

Type in Z values into the Sigma input box: 1/Z to convert Z values to Standard Deviations
