What sample size do you need for a binomial test of proportions?

Web30 Aug 2024 · I think you need a bigger sample to get that power. For example pbinom (6,177,0.07) gives 0.0322 while pbinom (7,177,0.07) gives 0.0668, so you would reject the null hypothesis of 0.07 if you saw 6 or fewer successes from a sample of 177. Then pbinom (6,177,0.03) gives 0.7172 which is rather less than 80%. Or perhaps I have misunderstood.
