Independent random samples were selected from two binomial populations, with sample sizes and the number of successes given below. n₁ = 1,450, n₂ = 1,300, x₁ = 555, x₂ = 636 Find the best point estimate for the difference in the population proportion of successes. (Use P₁ - P₂. Round your answer to four decimal places.) Calculate the 95% margin of error. (Round your answer to four decimal places.)
