  10. Inference on Two Population Proportions (I) &5-6 (&9-6) • Two independent random samples of size n1 and n2 are taken from two populations, and let X1 and X2 represent the number of observations that belong to the class of interest in samples 1 and 2, respectively. • For large samples, the estimation of the population proportions have approximate normal distributions. Statistics II_Five

  11. Inference on Two Population Proportions (II) • Therefore, is approximately standard normalization. • If H0: p1 = p2 is true, that is, p1 = p2 = p, then Statistics II_Five
