If mp₁, må₁, np₂, and nå2 are at least 10, we can use the large-sample test procedure with an approximately standard normal distribution. The variables m and n are the sample sizes of Brand A and Brand B, respectively, p₁ and ₂ are the sample proportions of non-contaminated chickens of Brand A and Brand B, respectively, and ₁=1 - p₁ and ₂ = 1 - ₂. Recall that 34 of 80 chickens from Brand A tested positive, so the number of non-contaminated chickens is 80 - 34 = 46 . The value of p₁ is the number of non-contaminated Brand A chickens divided by the total number of Brand A chickens, or p₁ = [ Calculate mp₁¹ mp₁ = 80( = Recall that 4₁ 1-p₁.
