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 ... View more
