WebWe have N = 580 and we want to estimate population proportion, p, at a 95%-CI and a margin of error of 0.10, then I get n = N p q / ( N − 1) D + p q where D = B 2 / 4 to be about n = 86. But what if instead we keep that same margin of error at 0.10 and now only want a 90%-CI, if we use the same formula don't we get the same n?
