During each execution of the following DO loop, the value of Earned is calculated and is added to its previous value. Determine the number of times the DO loop executes and the number of observations in the data set finance.earnings. data finance.earnings; Amount=1000; Rate=.075/12; do month=1 to 24; Earned+(amount+earned)*rate; end; run; a. loop executes 24 times, # of observations =1 b. loop executes 25 times, # of observations =24 c. loop executes 1 time, # of observations =1 d. loop executes 24 times, # of observations =24 e. loop executes 25 times, # of observations=1
a. loop executes 24 times, # of observations =1 only prints one observation for the amount earned with interest as of the 24th moth 24 loops since beginning with one, not zero. Can produce all loop intervals with explicit output statement: data finance.earnings; Amount=1000; Rate=.075/12; do month=1 to 24; Earned+(amount+earned)*rate; output; end; run;
Using ODS statements, how many types of output can you generate concurrently?
