Consider the following results for independent samples taken from two populations. Sample 1 Sample 2 n1 = 400 n2= 300 p1= 0.45 p2= 0.37 a. What is the point estimate of the difference between the two population proportions (to 2 decimals)? b. Develop a 90% confidence interval for the difference between the two population proportions (to 4 decimals). Use z-table. c. Develop a 95% confidence interval for the difference between the two population proportions (to 4 decimals). Use z-table

Step 1
Given: p1 = 0.45 p2 = 0.37 Point estimate = p1 - p2 Point estimate = 0.45 - 0.37 Point estimate = 0.08 Show more…

Consider the following results for independent samples taken from two populations. Sample 1: n1 = 400, p1 = 0.49. Sample 2: n2 = 300, p2 = 0.32. (a) What is the point estimate of the difference between the two population proportions? (Use p1 - p2.) (b) Develop a 90% confidence interval for the difference between the two population proportions. (Use p1 - p2. Round your answer to four decimal places.) (c) Develop a 95% confidence interval for the difference between the two population proportions. (Use p1 - p2. Round your answer to four decimal places.)
