Including continuity correction
If a random variable X has a binomial distribution with parameters n and p, i.e., X is distributed as the number of "successes" in n independent Bernoulli trials with probability p of success on each trial, then for any x ∈ {0, 1, 2, ... n}. If np and np(1 − p) are large (sometimes taken as both ≥ 5), then the probability above is fairly well approximated by WebFive continuity corrections (including zero) are considered with respect to each approach. The key properties of the corresponding methods are evaluated via simulations. First, the uncorrected two-sided confidence intervals can, potentially, have smaller coverage probability than the nominal level even for moderately large sample sizes, for ...

WebMar 17, 2024 · With the continuity correction, it's 0.031. Simulating the distribution produces a p-value of ~ 0.026. (One issue with this approach is that in R this simulation samples from a hypergeometric distribution which may not approximate your sampling situation.)
