The theory is thatramp metering controls the number of cars on the freeway and the number of cars accessing the freeway, resulting in a freer flow of cars, which ultimately results infaster travel times. To test whether ramp metering is effective in reducing travel times, engineers conducted an experiment in which a section of freeway had rampmeters installed on the on-ramps. The response variable for the study was speed of the vehicles. A random sample of 15 cars on the highway for a Monday at 6 p.m.with the ramp meters on and a second random sample of 15 cars on a different Monday at 6 p.m. with the meters off resulted in the following speeds (in miles perhour).E Click the icon to view the data sets.(a) Draw side-by-side boxplots of each data set.
