Given below in Data Set A are the initial LDL cholesterol level of each individual before receiving the drug or the placebo and the LDL reading 3 months after being placed on the drug/placebo. The patients are identified by a three digit code. After the patient code the LDL level of the patient is given, followed by a code that identifies if the LDL reading is the pre-drug/placebo reading (PRE) at zero months or the reading taken 3 months later (POST). Please note that two of the patients did not show up for the post drug/placebo testing.

DATA SET B 101 P 102 D 103 D 104 P 105 P 106 D 107 P 108 D 109 D 110 P 111 P 112 D Using only the SAS data sets you created in Part (a), create a data set that contains individual ID, before and after LDL levels, percentage reduction in the LDL level, and the whether each individual belongs to the Drug group or the Placebo group . Include SAS commands to print out this data set. No variables other than ID, Drug/placebo status, LDL level at zero months (PRE level), LDL level at 3 months (POST level), and Percentage Reduction should be included in the data set.
