Given two dependent random samples with the following results: Population 1 27 22 37 27 35 47 36 Population 2 32 46 20 38 49 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. 24 30
