Statistical significance of the difference

Reference no: EM13992933

The bitter, 8-month baseball strike that ended the 1994 season so abruptly was expected to have substantial reperC11$iOns at the box office when the 1995 season finally got under way. It did. By the end of the first week of play, American League teams were pl.Bying to 12.8% fewer faru; than the year before; National League teams fared even worse-their attendance was down 15.1% (200). Based on the team-by-team attendance figures given below, would it be appropriate to use Lbe pooled two-sample t test of Theorem 9.22 to a Lbe statistical significance of the difference between those two means?
