One of the basketball coaches at Cypress College wanted to see if Cypress College's Strength & Exercise class was increasing the weight that a player could bench press. The basketball coach randomly selected some of his players and determined how much they could bench press before taking the class. Then after completing the class, he again determined the weight that they could now bench press. The data for these players is given in the table below. Test whether the Strength and Exercise class is increasing the amount of weight that the players can bench press at the a=0.05 level of significance.
