Normal-scores plot. Use a computer program to make a normal-scores plot for the volume of timber data in Table 4. (Courtesy of Professor Alan Ek) Comment on the departure from normality displayed by the normal-scores plot.
TABLE 4
Volume of timber in cords

We illustrate a normal-scores plot using MINITAB. With the data set in column 1, the MINITAB commands

will create a normal-scores plot for the observations in CI. (MINITAB uses a variant of the normal scores, m1, that we defined.)
