A grassroots group opposed to a proposed increase in the gas tax claimed that the increase would hurt working-class people most, since they commute the farthest to work. Suppose that the group randomly surveyed 24 individuals and asked them th daily one-way commuting mileage. The results are below. Using a 5% significance level, test the hypothesis that the three mean commuting mileages are the same. (Let 1 = Working-class, 2 = Professional (middle incomes), and 3 = Professional (wealthy).) Part (a) Part (b) Part (c) Part (d) Part (e) Part (f) Working-class 18.1 27.5 49.7 10.1 65.8 47.2 20.1 51.8 Part (g) Professional (middle incomes) 17.0 17.5 22.7 7.6 10.2 2.9 7.3 14.5 What is the test statistic? (Round your answer to two decimal places.) What is the p-value? (Round your answer to four decimal places.) Professional (wealthy) 9.1 7.2 4.9 12.8 11.6 29.0 16.3 9.5
