About significance level in SAS

[oves]

Hi,
Let's assume:

Medicine A heals 60 of of 100.
Testing if medicine B is better.
Using level 0.05.
Wish to find the lowest number of healed to say: Yes, it is better!
The answer is 68, but...
How to best calculate this in SAS (using EG 7.15)?

Use PROC FREQ, and check its documentation 's example ,especial about Relative Risk Test.

proc freq data=have;

table Medicine*Yes_No / Chisq    riskdiff ;

run;

Here is for your question.

That's likely some basic math so you could take the formula and calculate it manually but I would likely be checking PROC POWER to see if it could calculate that number. Are you assuming that the groups are equally sized as well? Ie 100 people? I believe the denominator may be important as well. If it heals 68 out of 1000 that's different than 68 out of 100 so you may need to be looking at rates instead.
