Consider the following results for independent samples taken from two populations. Sample 1 Sample 2 n = 400 n, = 300 P, = 0.56| P2 = 0.39 (a) What is the point estimate of the difference between the two population proportions? (b) Develop a 90% confidence interval for the difference between the two population proportions. (c) Develop a 95% confidence interval for the difference between the two population proportions. p1 (a) What is the point estimate of the difference between the two population proportions? The point estimate for the difference between two population means is calculated as follows where p, is the sample proportion from population 1 and p, is the sample mean from population 2. P1 - P2 Ne are given p, = point estimate = P - P2 = 0.56 - .56 and p, = 0.39. Find difference.

Question
Consider the following results for independent samples taken from two populations. Sample 1 Sample 2 n1 = 400 n2 = 300 P1 = 0.56 P2 = 0.39 (a) What is the point estimate of the difference between the two population proportions? (b) Develop a 90% confidence interval for the difference between the two population proportions. (c) Develop a 95% confidence interval for the difference between the two population proportions. Step 1 (a) What is the point estimate of the difference between the two population proportions? The point estimate for the difference between two population means is calculated as follows where p, is the sample proportion from population 1 and p, is the sample mean from population 2. P1- P2 We are given = 0.56 and p, = 0.39. Find the difference. point estimate = P1 - P2 = 0.56 –
