You may need to use the appropriate technology to answer this question. Consider the following hypothesis test. H0: μd ≤ 0 Ha: μd > 0 (a) The following data are from matched samples taken from two populations. Compute the difference value for each element. (Use Population 1 − Population 2.) Element Population Difference 1 2 1 21 19 2 Correct: Your answer is correct. 2 28 25 3 Correct: Your answer is correct. 3 18 15 3 Correct: Your answer is correct. 4 20 19 1 Correct: Your answer is correct. 5 26 25 1 Correct: Your answer is correct. (b) Compute d. 2 Correct: Your answer is correct. (c) Compute the standard deviation sd. 0.89 Incorrect: Your answer is incorrect. (d) Conduct a hypothesis test using α = 0.05. Calculate the test statistic. (Round your answer to three decimal places.) 5 Incorrect: Your answer is incorrect. Calculate the p-value. (Round your answer to four decimal places.) p-value = 0.9999 Incorrect: Your answer is incorrect. What is your conclusion? Do not reject H0. There is insufficient evidence to conclude that μd > 0. Do not Reject H0. There is sufficient evidence to conclude that μd > 0. Reject H0. There is sufficient evidence to conclude that μd > 0. Reject H0. There is insufficient evidence to conclude that μd > 0. Correct: Your answer is correct.
