For any signi cance level , if the p-value for the data found is less than , then there is enough evidence to reject the null hypothesis at signi cance level .
WebJun 17, 2015 · The binomial test is an exact test that uses the binomial distribution to get an exact count of how often p ^ would happen under the null hypothesis. You can run it in R using binom.test. It makes no assumptions about n p or n ( 1 − p). However, since it is an exact test, not every p-value is possible. Share.
