Problem # 3

Nike just introduced a new glove that claims that wide receivers and
defensive backs will be able to catch more footballs due to Nike’s
new sticky compound placed on the gloves. Eight players are
recruited to participate in the study. In the first test, the players
catch the footballs using their bare hands and the second test the
players use the new gloves. The data presented are the number of
footballs caught (out of 100) for each test. Determine if the gloves
increase the number of footballs caught by the players (use  = .05).
