"One common use of the binomial test is in the case where the null hypothesis is that two categories are equally likely to occur (such as a coin toss), implying a null hypothesis . Tables are widely available to give the significance observed numbers of observations in the categories for this case. However, as the example below shows, the binomial test is not restricted to this case. When there are more than two categories, and an exact test is required, the multinomial test, ba… " - Null hypothesis binomial distribution
