3- For each of the studies above, explain when a type 1 error occurs and when a type 2 error occurs.

4- Let's assume that in reality your null hypotheses statements for studies (a) and (c) in question 2 are correct and the alternative hypotheses statements for studies (b) and (d) are correct. Which studies (a, b, c, or d) can lead to a type 1, and which studies can lead to a type 2 error?
