STATISTICAL TESTS

Steps for performing a one-small-sample hypothesis test for the population mean

1. Turn the calculator on and access the data entry screen. Delete old data

and enter the following data set for L1:
7	10	7	6	8	10	15	14	11
12	6	11	11	5	7	9	9	7

2.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 in each season since 1978.

3.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 (8 wins).

7.The first item on the screen, µo>8, is the alternate hypothesis of the statistical test. The second item on the screen is the observed statistic from the sample. The third item on the screen is the decision statistic or p value.

8.The p value is .0482, which is less than .05. Our decision is to reject the null hypothesis that µo=8 and support the alternate hypothesis that µo>8. This test clearly shows that "da Bears" average more than 8 wins a season and thus are a winning football team. The fourth item shows that on the average, "da Bears" win approximately 9 games a season.
