What is hypothesis? Give an example of a hypothesis test. You may choose an example from the textbook, an example from another source, or your own example. Be sure that you provide a citation for any example used.

Identify each of the following for the hypothesis example you provide:

1) null hypothesis – Explain this null hypothesis. Explain what the alternative hypothesis is. Explain what rejecting the null hypothesis would allow you to conclude.

2a) test statistic utilized – Specify what distribution (z, t, chi-squared, F, etc is considered) is considered.

2b) test statistic cut-off – What is the percent confidence and what value does that give for the border between rejecting and failing to reject the null hypothesis?

2c) test statistic calculated – What value does the test statistic have for the data?

3) decision – Is the calculated test statistic greater than or less than the cut-off value? Do you “reject” or “fail to reject” the null hypothesis?

4) explanation – Explain what this decision means in the context of the problem. Be sure you include the percent confidence and the null/alternative hypothesis in your explanation.
