Use the normal probability plot in Figure 4.49, based on the variable systolic blood pressure in the Intensive Care Unit data set (???? = 200), to answer the following:

(a) Does the normal probability plot in Figure 4.49 pass the “fat pencil test”?

Explain.

(b) Does the normal probability plot in Figure 4.49 support the use of the normal probability model? Explain.

(c) Estimate the median of the distribution of the variable systolic blood pressure.

(d) Estimate the 10th percentile of the distribution of the variable systolic blood pressure.
