Question: Z-value for testing p1 - p 2 = d 0 : To test the null hypothesis Ho that p 1? - p 2 = do,

Z-value for testing p1 - p₂ = d₀: To test the null hypothesis Ho that p_1?- p₂ = do, where do ? 0, we base our decision on which is a value of a random variable whose distribution approximates the standard normal distribution as long as n₁ and n₂ are both large. With reference to Example 10.12, test the hypothesis that the percentage of town voters favoring the construction of the chemical plant will not exceed the percentage of county voters by more than 3%. Use a P-value in your conclusion.
