The data shown above reflects the number of wins for the Chicago Bears and Green Bay Packers in each season since 1978 when the NFL went to a 16 game season. The only season left out was the 1982 strike shortened season. Test the alternate hypothesis that "da Bears" are a better (on the average won more games) football team than the Packers during these recent years. Each won one Super Bowl during this time. The null hypothesis would be that "da Bears" are merely equal to the Packers.
