Check the data you have entered and correct any errors you may find.

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.

Set up the statistical test by pressing 2ndF QUIT STAT , touching E TEST, and double touching 04 Ttest2samp. The two-sample T test was chosen because we have two small samples.

the standard deviations for the statistical test when the standard deviations are approximately equal. Statistical analysis of each data set showed they were nearly the same. Do not pool the standard deviations when they are subjectively

unequal. Set the List1 to L1 by pressing ▼ L2 by pressing 2ndF L2 ENTER .
