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. Estimate the mean difference in traffic count between the 6th and the 13th using a 95% level. Round to the nearest whole number. Traffic Count With Dates 6th 117466 131106 128632 13th 118487 130120 126751 119933 120174 1991, December 118310 118650 1991, December 117044 117470 1992, March 132858 128682 1992, March 130086 129314 120605 118975 1992, November 1992, November 136695 132442 1990, July 1990, July 1991, September 1991, September % confidence, it can be said that the true mean difference in traffic count and between the 6th and the 13th is between
