As the pace of college football has increased over the years, the number of plays per game appears to have increased. To test this theory, random samples of college football games were selected from the 2006 season as well as the 2012 season. The total number of plays made in each game was counted and the data are as follows. These data can also be found in the Excel file football plays.xlsx.

Using α = 0.05, can we conclude that the median number of plays per game increased from the 2006 to the 2012 season?
