Investigation 1: Ezpass on I-66 Transportation engineers
determined that to help ease traffic, they would set up tolls for
solo drivers during rush hour times on Route I-66 inside the
Capital Beltway (Route I-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 I-66
after the program began, a count of the number of vehicles was
collected from two random samples. One sample collected the number
of daily vehicles for 12 randomly selected days prior to December
4, 2017 (“Before”) and a second sample collected the number of
daily vehicles for another 12 randomly selected days after December
4, 2017 (“After”) (up to a year after). The data set is called
“Number of Vehicles 1.” Use the significance level  = 0.05.
