Sharp Conducting Statistical Tests with the EL-9600 Calculator

The data shown above reflects the number of wins for the Chicago Bears 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 winning football team against the null hypothesis that "da Bears" are merely a .500 ball club.

Set up the statistical test by pressing 2ndF QUIT STAT , touching E TEST, and double touching 03 Ttest1samp. The one-sample T test was chosen because we have one small sample and we do not know the standard deviation. If we had a sample larger than 30 or knew the standard deviation, then we could use the Ztest1samp command. If we had two small samples or did not know the standard deviations, then we would use Ttest2samp. If we had two large samples or knew the standard deviations, then we could use the Ztest2samp. All of these tests are for testing equality of a mean to a number (one sample test) or equality of two means (two sample).

Set the alternate hypothesis to µ > µo by pressing

▼ ▼

ENTER . Set the null

hypothesis equal to 8 wins by pressing ▼ 8 ENTER . The null hypothesis was set equal to 8, since eight wins would represent a .500 season. Set the List to L1 by pressing 2ndF L1 ENTER .

Press 2ndF EXE to compute the statistical test. The following results will be displayed.
