Question
The speeds on Highway 401 east of Toronto average 110 km/hr with a standard
deviation of 7.1 km/hr and a coefficient of variation of 6.5%. The speeds on
Toronto's city streets average 28 km/hr with a standard deviation of 4.8 km/hr.
Which of the roads has a lower relative dispersion?
The city streets because the standard deviation of the city streets is only 4.8
km/hr compared to the highway at 7.1 km/hr.
Highway 401 because its coefficient of variation is only 6.4%, compared to the
city street at 17.1%.
O Unknown. The highway and the city streets cannot be compáred due to the
significant difference in the speeds of the vehicles using each.
The city streets because the city streets have a coefficient of variation of 5.8%
compared to the highway at 6.5%.
