Question
The British Department of Transportation studied to see if people avoid driving
on Friday the 13th. They did a traffic count on a Friday and then again on a
Friday the 13th at the same two locations. The data for each location on the
two different dates is in the table. Do the data show that on average fewer
people drive on Friday the 13th? Test at the 5% level.
