In order to estimate the difference between the average yearly incomes of marketing managers in the East and West of the United States, the following information was gathered. East West n1 = 40 n2 = 45 = 72 (in $1000) = 78 (in $1000) s1 = 6 (in $1000) s2 = 8 (in $1000) a. Develop an interval estimate for the difference between the average yearly incomes of the marketing managers in the East and West. Use 98% confidence. b. At α = .02, use the p-value approach and test to determine if the average yearly income of marketing managers in the East is significantly different from those in the West.
