PH6420 Summer: Assignment 6 Due: December 5 Overview This assignment will give you experience in performing basic statistical analyses using SAS. Hand in the program for Parts A and B and answer all questions. PART A: 1. Create a SAS dataset reading in the variables group, pulsebl, pulse12, potassbl, potass12 , and se12_10 ( cough at 12 months ) from tomhs.data (or use the tomhs permanent SAS dataset). Use LRECL=400 on the INFILE statement if you use the raw data file since the variable se12_10 is beyond the 256 th position. Reminder: group 1 = beta-blocker; 2= calcium channel blocker; 3=diuretic; 4=alpha blocker; 5=ace inhibitor; 6=placebo. 2. Compute new variables for the change in pulse and change in potassium (12 month values – baseline). Compute a new variable called hcough12 equal to 1 if se12_10 (cough) = 2,3 or 4 and equal to 2 if se12_10 = 1. 3. ACE inhibitors (group=5) are reported to cause cough. Test this using a chi-square test that compares the cough rate at 12 months between the ACE group and all other groups
