Answer to Question #748 in Statistics and Probability for Karen
If you determine that for the graph of a std. normal distribution, the cumulative area to the left of a z score is 0.4, what is the cumulative area to the right?
The area under the graph of the normal distribution function equals to the probability. The total probability (total area) equals to 1.Thus cumulative area to the right of z-score would be 1 - 0.4 = 0.6
