Question
1) Why does the comparison distribution change from normal to kurtotic when switching from a one-sample z-test to a one-sample t-test? 2) Provide an example of a research question relevant to your academic or career interests that is appropriate for a dependent means t-test and explain why it is appropriate for that inferential test (i.e., why is the structure of the research question well-suited for a dependent means t-test?). 3) Provide an example of a research question relevant to your academic or career interests that is appropriate for an independent means t-test and explain why it is appropriate for that inferential test (i.e., why is the structure of the research question well-suited for an independent means t-test?). 4) Provide an example of a research question relevant to your academic or career interests that is appropriate for a chi-squared test for independence and explain why it is appropriate for that inferential test (i.e., why are the variables and research question well-suited for a chi-squared test for independence?).
