Given two dependent random samples with the following results: Population 1 22 39 20 34 43 17 45 Population 2 33 45 35 46 35 27 37 Use this data to find the 98% confidence interval for the true difference between the population means. Let d = (Population 1 entry)-(Population 2 entry). Assume that both populations are normally distributed. Co Step 2 of 4: Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.
