Use the normal probability plot in Figure 4.48, based on the variable Density in theBody Fat data set (???? = 252), to answer the following questions.

(a) Does the normal probability plot in Figure 4.48 pass the “fat pencil test”?

Explain.

(b) Does the normal probability plot in Figure 4.48 support the use of the normal probability model? Explain.

(c) Estimate the median of the distribution of the variable Density.

(d) Estimate the 95th percentile of the distribution of the variable Density.
