This week's Introduction about a NASA rocket provided an example of when a t test may be used in a real-life situation. In this Discussion, you will analyze a research question of your choice using a t test.
To prepare for this Discussion:
Review problems which show how t tests can be used to analyze real-life data. Think about how you might answer each of the questions.
Think about one small data set that you would like to compare to a proposed mean. For example, you could compare the mean weight of a bag of chocolate chip cookies to the mean that the industry claims. Clearly outline your null and alternative hypothesis statements.
Consider why your research question is important.
Outline how you would use each of the steps of the four-step hypothesis test process to answer the research question.
Think about how using a t test could help your analysis. How is the outcome from the t test used to support the claim made?
