WebThe conditions n*p > 10 and n*q > 10 ensure that p is not too close to 0 or 1. For any given value of n, if p is too close to 0 or 1, then the distribution of the number of successes in a binomial distribution with n trials and success probability p would be significantly asymmetric about its mean (and so significantly non-normal). 4 comments. http://jse.amstat.org/v21n1/wroughton.pdf
