1) Green Line: The Slope of the line represents Z values while the Y-intercept represents Standard Deviations ( Must type in values from the equation of the Green Line into the Sigma input box to correlate data as instructed in Step 2 )
2) Type in the Y - intercept of the Green Line into the Sigma input box or Type in the Slope of the Green Line into the Sigma input box as: 1 / Slope(x) which the slope represents z values while the Y-intercepts are the Standard deviations.
3) Notice that the probabilities in the Blue box equal the probabilities under the normal curve; area " n "
4) Notice probabilities in Blue box = area " O " / Sigma
5)Notice how the Z values are calculated using Cumulative area's ( See Limits of Integration )
Study the distributions and their relationships
