Consider the following results for independent samples taken from two populations. Sample 1 Sample 2 n1 = 400 72 = 300 P1 = 0.49 P2 = 0.34 (a) What is the point estimate of the difference between the two population proportions? (Use P] - P2.) (b) Develop a 90% confidence interval for the difference between the two population proportions. (Use P, - P2. Round your answer to four decimal places.) to (c) Develop a 95% confidence interval for the difference between the two population proportions. (Use P1 - P2.

Tutorial Exercise You may need to use the appropriate appendix table or technology to answer this question. Consider the hypothesis test. o P1 - P2 S Ha: P1 - P The following results are for independent samples taken from the two populations. Sample 1 Sample 2 71 = 200 n2 = 300 P1 = 0.23 P2 = 0.15 (a) Calculate the test statistic. What is the p-value? (b) With a = 0.05, what is your hypothesis testing conclusion
