hypothesis test

[ying2]

Hi,

I am a new user of SAS. 

I got a data like

                                  Prominent wrinkles              wrinkles not prominent                  

Heavy smoker                95                                         55

Light or nonsmoker      103                                        247

Now I want to do a hypothesis test using this data. I am thinking I might should use proc ttest. But I only know how to deal with one numerical like score or something. 

Anyone could help me with the coding? 

Thank you

Test of what hypothesis? Please be specific.

Please show us the exact SAS data set (or a portion of it).

That is all data I got. And the question is" Do these data substantiate an association between wrinkle formation and smoking habit"

You have a 2x2 table, you should likely be using Chi Square tests and PROC FREQ.

proc freq data=Have;
tables Smoker_Status * Wrinkle_Status / norow nocol chisq;
run;

Use PROC FREQ
