Base SAS Example Question 1.1

Hi everyone,

I'm going to start posting example questions for the Base SAS exam about once a week. The questions will test information covered in the SAS Certification Prep Guide, and I'll provide the answers to these questions about a week or two after they're originally posted.

Please leave a comment below this post with your answer - hopefully this will start a good discussion from fellow SAS programmers who are studying for the Base SAS Certification.

Good luck!
