1. The Los Angeles Heart Study is a prospective study of heart disease among Los Angeles employees. Write a descriptive report (3 pages or less) that compares subjects who survived to 1968 with subjects who died based on the subjects characteristics (age, weight, and diastolic blood pressure) in 1950. In the process, create a permanent SAS data set called LA1.SD2 (that is labeled). Include a copy of your SAS program(s) in an appendix.
2. Cody and Smith (1997, p45) discuss an example of a study conducted in a classroom setting where students are measured at two times (pretest and posttest) and provide some example data. There is interest in summarizing the mean pretest, postest, and gain (posttest-pretest) scores for each teacher. Write a brief report that presents these results, and save the data as a permanent SAS data set named csp45.sd2. Include a copy of your SAS program(s) in an appendix.
