Transportation engineers determined that to help ease traffic, they would set up tolls for solo drivers during rush hour times on Route 1-66 inside the Capital Beltway (1-495). Carpooling drivers with the proper Ezpass would drive free. The toll program began in December 4, 2017. To test the claim that fewer vehicles would use Route 1-66 after the program began, a count of the number of vehicles were collected from two random samples. Both samples were taken on the first Monday of each month for an entire year before and after the toll program was implemented. The data set is called “Number of Vehicles 2” and we will use a = 0.05 in this investigation.
