Question details

The numbers of successes and the sample sizes for independent simple random samples from two populations are provided for a right-tailed test. Use a 90% confidence interval. Complete parts (a) through (c). x1-24, n1-80, x2-22, n2 : 100, α = 0.05 a. Determine the sample proportions Determine the sample proportion p1 p1 p1-D( Round to three decimal places as needed.) threeThe numbers of successes and the sample sizes for independent simple random samples from two populations are provided for a right-tailed test. Use a 90% confidence interval. Complete parts (a) through (c). x1 = 15, n! =40, x2 = 10, n2 = 70, α = 0.05 a. Determine the sample proportions Determine the sample proportion p1 p1 0.375 (Round to three decimal places as needed.) Determine the sample proportion p2 2 0.143 (Round to three decimal places as needed.) Determine the pooled sample proportion p Pp 0.227 (Round to three decimal places as needed.) b. Use the two-proportions z-test to conduct the required hypothesis test. What are the hypotheses for this test? B Ho: P1 P2. Ha P1P2 Calculate the test statistic.Calculate the test statistic z- 3.18 (Round to two decimal places as needed.) Find the critical value(s) when α: 0.05. 1.645 Round to three decimal places as needed. Use a comma to separate answers as needed.) Which of the following is the correct conclusion for the hypothesis test? 0 A. At the 5% significance level, reject Ho, the data do not provide sufficient evidence to accept Ha. B. At the 5% significance level, do not reject Ho, the data provide sufficient evidence to accept Ha. C. At the 5% significance level, reject Ho, the data provide sufficient evidence to accept Ha. D. At the 5% significance level, do not reject Ho, the data do not provide sufficient evidence to accept Ha. c. Use the two-proportions z-interval procedure to find the specified confidence interval The 90% confidence interval for p1-p2 is from Round to three decimal places as needed.) 0.088 to 0.376.
