Many people who are involved with Major League Baseball believe that Yankees baseball games tend to last

Question:

Many people who are involved with Major League Baseball believe that Yankees€™ baseball games tend to last longer than games played by other teams. In order to test this theory, one other MLB team, the St. Louis Cardinals, was picked at random.The time of the game (in minutes) for 12 randomly selected Cardinals€™ games and 14 randomly selected Yankees€™ games was obtained.

Do these samples provide significant evidence to conclude that the mean time of Yankees€™ baseball games is significantly greater than the mean time of Cardinals€™ games? Use a = 0.05.
