Description: After the AFC championship game on January 18th, 2015, there was a controversy about whether the New England Patriots might have deflated their footballs during the game to gain an advantage. During the game with the Indianapolis Colts, two officials, Blakeman and Prioleau, measured the PSI in 11 balls from the Patriots and 4 balls from the Colts. These measurements are included in this data set. The Patriots balls are labeled with a "P" prefix, and the Colts balls are labeled with a "C" prefix. The official rules of the National Football League require footballs to be inflated to between 12.5 and 13.5 PSI. Does this data set support the deflation claim?
