1.2 You have collected the following information on some participants in a diet program: Variable Name Description Type Starting Column Ending Column SUBJ Subject number Character HEIGHT Height in inches Numeric WT_INIT WT_FINAL Initial weight (in pounds) Final weight Numeric Numeric 3581 (a) Reading the following data lines, create a SAS data set using column input. Include in this data set three computed variables called BMI INIT (BMI stands for body mass index), BMI FINAL, and BMI DIFF. Computed BMI is a person's weight (in kilo- grams) divided by their height (in meters) squared. To convert pounds to kilograms, di- vide by 2.2; to convert inches to meters, multiply by .0254. BMI DIFF is BMI FINAL minus BMI_INIT. Note: Large values of BMI indicate more overweight individuals. Therefore, if the diet program is working, BMI DIFF should come out negative. (b) Print out a listing of this data set in subject number order. Include in the listing only the variables SUBJ, HEIGHT, BMI_INIT, BMI FINAL, and BMI DIFF. Here is some sample data for you to use: 00768155150 00272250240 00563240200 00170345298
