Describe the null hypothesis for the test of independence. List the assumptions for the χ2 test of independence. What is the major difference between the assumptions for this test and the assumptions for the previous tests we have studied?

Describe the assumptions that should be met when deciding to use the t-test (i.e., scale of measurement; assumptions about variances of groups being compared; assumptions about group sizes; shapes of distributions.)

Step 2 of hypothesis testing involves reviewing the assumptions of 2 sample t-test. Discuss the three assumptions of the t-test. Provide an example of the assumption that is not robust to violations and a situation when the assumption is violated.

Explain why we must verify whether or not the assumptions of an inferential statistical test are met before we calculate the statistic. Specifically, what does a failure to meet the assumptions mean in terms of the α level of our experiment? What should we do if the assumptions are not met?
