$($a$)$ Reading the following data lines, create a SAS data set using column input. Include it this data set three computed variables called BMI$\_$INIT $($BMI stands for body 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 if vide by $2\mathrm{.}2$; to convert inches to meters, multiply by $\mathrm{.}0254.$ BMI$\_$DIFF is BMI$\_$FINL minus BMI$\_$INIT. Note: Large values of BMI indicate more overweight individuls 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 onty the variables SUBJ, HEIGHT, BMI$\_$INIT, BMI$\_$FINAL, and BMI$\_$DIFF. Here is some sample data for you to use:
