Normal vs RVsigma - It shows here that RVsigma can be = to the standard deviation of the Normal Curve as I have stated that it is!
Here I have shown that the Normal Curve and RV Sigma exactly overlay each other as the two Graphs show at top.
1) Data on the Right shows data from the Triangle, I^2 , Normal, Sigma Probabilities
2) Data consist of ' t ' - test and General Statistics
3) Study Ledgers in each graph
4) Look at Data Carefully
