d. No, there is a difference between the percents in two types of transportation - Car and Bus categories, depending on the Job Classification.
Car Bus Train
Management 28.9 22.2 48.9
Labor 17.0 32.1 50.9
Although about half of each group take the train, management are more likely than labor to come by car and less likely to take a bus.
