OK, say it turned out 10% c diff, then what? Would you want to test that result for significance? What would a 'significant' result mean in your case?

comment Power/sample size calculation for one group prospective study
You may well be missing something. Perhaps we can help you figure out what it is. What is it you ultimately want to do? (Ie, imagine you have done the study & you have all the data, what are you going to do next?)

comment When is beta distribution bell-shaped?
(I assume you mean concave down.) In that case, the black line would also be considered 'bell-shaped' even though it's skewed. Also, a bi-modal beta dist, so long as it's concave down, counts as 'bell-shaped', is that correct?

comment When is beta distribution bell-shaped?
What I was hinting at is that you need a precise definition of 'bell-shaped' in order for this question to be answerable. Eg, is what you want any shape that has exactly 0 skewness & is unimodal?
