Web$\begingroup$ @DanWu, you’re right that the binomial test is more cumbersome to work with for large n, but this only true if you’re calculating the results by hand.As long as you use R, there is no problem. And for large n it doesn’t matter, as both functions give approximately the same answer. But do note that prop.test() uses the score test, not a … In statistics, a binomial proportion confidence interval is a confidence interval for the probability of success calculated from the outcome of a series of success–failure experiments (Bernoulli trials). In other words, a binomial proportion confidence interval is an interval estimate of a success … See more A commonly used formula for a binomial confidence interval relies on approximating the distribution of error about a binomially-distributed observation, $${\displaystyle {\hat {p}}}$$, with a normal distribution.
