11.46 Goodness of fit to a binomial distribution. B(n, p), B(n, p), is a model for the distribution of the count, X,X, of successes in a sample of size nn- where the probability of success is p.P. Use statistical software to generate 500 observations from the B(3, 0.4)B(3, 0.4), distribution and perform the goodness-of-fit test for these data.
