Given two dependent random samples with the following results: Population 1 43 32 39 Population 2 34 19 36 29 46 35 41 39 39 44 47 37 Use this data to find the 90% 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. Copy Data Step 1 of 4: Find the mean of the paired differences, d. Round your answer to one decimal place.
