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.
Set the alternate hypothesis to µ1 > µ2 by pressing ENTER . Pool the
standard deviations in the calculation by pressing ENTER . We pool
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 2ndF L1 ENTER . Set List2 to
L2 by pressing 2ndF L2 ENTER .
