Use the Intensive Care Unit data set to identify potential differences in the subpopulations of systolic blood pressure (SYS) due to each survival status (STA)

by

(a) creating histograms and boxplots of systolic blood pressure for each survival status.

(b) estimating the mean, median, and standard deviation of the variable systolic blood pressure for each survival status.

(c) using the information in part

(b) to estimate the boundaries of the two standard deviation empirical rule (i.e., ???? ± 2????).

(d) using parts (a)–

(d) to estimate potential differences in the systolic blood pressure of patients admitted to the intensive care unit who survived and who did not survive.
