Hi,

Plenty of folks here are happy to help with homework assignments. But most don't want to do the homework for you. Have you worked on this? Are you having problems? Please show code you have tried, and describe the problems (errors? unexpected results?) That will make it easier for people to help you.

Hello, thank you for your response.

That's not homework. It's an extra credit. I have never used a SAS so II don't really know where to start

First step would be to read the data from the Excel file into a SAS datasets. Probably the easiest way is with the LIBNAME statement using the XLSX engine. Have you done that? After you have read it in, look into PROC FREQ, PROC UNIVARIATE, and PROC MEANS.

But if you've literally never used SAS before, you may want to ask a colleague for help getting started.

There are plenty of tutorials available here at sas.com and on YouTube to get you started. And yes, extra credit is indeed homework.
