with the medium cuff an unexpectedly large amount of people showed a SBP of at least 140mmHG and with the large cuff a value, which was within whatever significance value they were testing, it is obvious that is what they did, it's pretty much the only test they could do. Even if they didn't do that test, you could do that test and come to the same conclusion. Brb finding out mean and variance of blood pressure so I can just do the test.
OK sbp in teh mexicans has a mean of 122. variance is proving harder to find.
