Using t Tests
This week's Introduction about a NASA rocket provided an example of when a t test may be used in a reallife situation. In this Discussion, you will analyze a research question of your choice using a t test.
To prepare for this Discussion:
 Review problems 17–24 on pages 416–417 of your text, which show how t tests can be used to analyze reallife data. Think about how you might answer each of the questions.

 Think about two small sets of reallife data that you could compare and analyze using a t test. This could include information you have read about that you are interested in testing. For example, think of data that could answer the question, "Does Product A really perform better than Product B?" or "Are the temperatures during a certain week in my city really that different from its temperatures 50 years ago?"

 Consider why your research question is important.

 Identify the dependent and independent variables.

 Determine how you would use the fourstep hypothesis test process to answer the research question.

 Think about how using a t test could help your analysis.
With these thoughts in mind:
Post by Day 3 a 1 to 2paragraph writeup including the following:
 Describe your research question, and explain its importance.
 Identify the dependent and independent variables of the question you chose.
 Describe how you would use the fourstep hypothesis test process to answer your research question.
 Explain how using a t test could help you answer your research question.
