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.

Find the p-value. Round to four decimal places. p-value = State your decision. O Since the p-value is greater than .05, fail to reject Ho. Since the p-value is less than .05, reject Ho. Since the p-value is greater than .05, reject Ho. O Since the p-value is less than .05, fail to reject Ho. Interpret the results. O At the 5% level of significance, there is enough evidence to show that on average more people drive on Friday the 13th. At the 5% level of significance, there is not enough evidence to show that on average a different number of people drive on Friday the 13th.
