Reference no: EM13473270

A1 limousine service offers service to and from Newark airport to Princeton New Jersey. John Wheels, the president of A1 limo, is considering two routes to Princeton. One route via US 1 and the other is via the NJ Turnpike. He is interested in the amount of time it takes to drive to the airport using each route and then compare the results. He instructed his drivers to drive using both routes and record the time (in minutes) it takes the drivers to arrive at Princeton. The table below shows the travel time

Route US 1 NJ Turnpike

100 90

95 100

120 95

75 90

Using the 0.05 significance level, is there a difference in the variation in the driving times for the two routes? ( 120 points.)
