Document Summary
Calculate p = x/n where x = number of successes and n = sample size. Check n 0 10 and n(1 0) 10 to ensure normality (some textbooks say 5 is sufficient). If you have sampled more than 5% of the population without replacement, use the finite population formula. = n 1 and assumes that the sample items are drawn from a normal population, but the test is fairly robust to non-normality. If you have sampled more than 5% of the population without replacement, use the infinite population formula. The chi-square test is sensitive to skewness. n.
