(A review on SAS data management) The following is a data set of12 individuals. And we want to relate the heart rate at rest (Y) tokilograms body weight (X). X Y 90 62 87 41 87 63 73 46 73 53 86 55100 70 75 47 76 49 87 69 79 41 78 48 Write a program in SAS whichread the given data set into SAS library. In your program, create anew data set which is a copy of the first, with the addition of anew variable which represents the weight in pounds (1 kilogram≈2.2pounds). Use “proc print” to view the data for all three variables.(c) Create a new variable called weight_group which divides thedata set into four groups based on the estimated quartiles for thevariable weight. The estimated quartiles may be requested using thekeywords q1, median, and q3, in the “proc means” statement. (d) Use“proc freq” to summarize the frequency of subjects in each of thefour groups. (e) Obtain the mean and standard deviation for theheart rate at rest for each of the four groups. Comment on theresults. (f) Produce a scatterplot of the heart rate at rest versusbody weight in kilograms. Describe what you see. (g)Fit a straightline model for heart rate at rest versus body weight in kilograms.Comment on the fit of the line.
