You may need to use the appropriate appendix table or technology to answer this question. Recall the method used to obtain a confidence interval for the difference between two population means for matched samples. (a) The following data are from matched samples taken from two populations. Compute the difference value for each element. (Use Population 1 - Population 2.) Population Element Difference 11 6 2 7 5 3 4 4 12 5 5 13 8 6 15 13 15 12 (b) Compute d. (c) Compute the standard deviation s. (Round your answer to two decimal places.) (d) What is the point estimate of the difference between the two population means? (Use Population 1 - Population 2.) (e) Provide a 95% confidence interval for the difference between the two population means. (Use Population 1 - Population 2. Round your answers to two decimal places.) toYou may need to use the appropriate technology to answer this question. Consider the following hypothesis test.

Population Element Difference 21 19 2 28 27 3 18 18 4 20 18 5 26 26 (b) Compute d. (C) Compute the standard deviation s. (d) Conduct a hypothesis test using a = 0.05. Calculate the test statistic. (Round your answer to three decimal places.) Calculate the p-value. (Round your answer to four decimal places.) p-value - What is your conclusion? O Reject Ho. There is insufficient evidence to conclude that # > 0. Do not reject Ho. There is insufficient evidence to conclude that # > 0. O Reject H . There is sufficient evidence to conclude that Ho > 0. Do not Reject Ho. There is sufficient evidence to conclude that # 2 0Step by Step Solution
