Plot the 5%/50%/95% plotting points. 1. Prepare Col. 4 from Table 2-.a(B). Plot the points. 2. Sketch the envelope through the 5% 2. See curves #1 and #3, plotting points and through the 95% plotting points. There seems little point in going on with thti analysis, the lines are so curved that it doesn't seem that the data came from a s-normal distributioki. This conclusion is c,,trary to the ones drawn from the K-S Bounds method for the same data.
In gen- eral, one should tend to believe the K-S Bounds method. In subsequent paragraphs, the Wetbull and lognormal distributions will be tried for Data Sets A, B, C to see if they fit better. |'• " .11
