For the binomial test, p = q. For binomial data that satisfy the criterion for using the normal approximation, you can either compute a Z-score or a value for chi-square. The relationship between the two statistics is z = x². The binomial distribution with p = .10 has a mean of u = 10. For this distribution, there are n = in the sample. 1000 scores
