Consider the following SAS data step:

data result;

input Type C1 C2 ;

datalines;

502 731

.00

;

proc print;

Display appearance of the output from the print if each of the following sets of statements, respectively, appeared between input and datalines; when the program is executed:

a. Index = (2*C1) + C2;

b. if Type <= 6 then do;

Index = (2*C1) + C2;

output;

end;

c. if Type <= 6 then do;

Index = (2*C1) + C2;

end;

else delete;

d. if Type > 6 then delete;

e. if Type > 6 then delete;

Index = (2*C1) + C2;
