Binomial Distribution Chi Square Test. In some circumstances the chi square test can be replaced by a test based on the binomial distribution. Binomials contingency tables chi square tests p 1 16.
I do this for two tests one in which the probability of success is specified in the null hypothesis and one where it is estimated from the data. I work through an example of testing the null hypothesis that the data comes from a binomial distribution. If we want to see whether 0 20 is too high a probability of heads when we observe 5 heads out of 50 tosses we use binom test 5 50 0 2 which gives probability of 5 or fewer heads as 0 09667 so a test does not exclude 0 20 as the heads probability.
To work out a confidence interval on binomial proportions use binom test.
5 and 50 number of. 5 and 50 number of. The binomial test is an exact test to compare the observed distribution to the expected distribution when there are only two categories so only two rows of data were entered. Binom test 5 50 0 2 exact binomial test data.
