hypothesis test

ying2 — Tue, 22 Oct 2019 12:08:32 GMT

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).

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

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