Binomial test hypothesis

WebBinomial hypothesis tests compare the number of observed “successes” among a sample of “trials” to an expected population-level probability of success. They are used for a sample of one binary categorical variable. For example, if we want to test whether a coin is fair, we might flip it 100 times and count how many heads we get. WebIn this case, test statistics are repeatedly simulated from a multivariate normal distribution under the joint null hypothesis, converted into one- or two-sided \(p\)-values (depending on the side argument), and the binomial test is applied.
