graphing calculator is recommended. grassroots group opposed to a proposed increase in the gas tax claimed that the increase would hurt working-class people the most, since they commute the farthest to work. Suppose that the group randomly surveyed 24 individuals and asked them their 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).) Working-class Professional (middle incomes) Professional (wealthy) 19.5 18.2 10.2 28.4 19.1 7.6 50.5 23.1 5.9 10.8 9.2 14.2 66.7 10.5 12.1 48.9 3.7 30.4 21.1 8.0 17.3 .1.5:2.. 10.9 + Part (a) + Part (b) [+) Part (c) + Part (d) (+) Part (e) Part (f) What is the test statistic?
