Question: The professor also wants to examine if there are differences in course points based on delivery environment (online, residential) and race. If he finds differences, then he may realize 1) that he will need to evaluate his course ethnic sensitivity, 2) that he may be a more effective teacher in one environment than another, 3) that he needs to adapt some of his teaching methods, and 4) that one learning environment may be more effective for one race than another. As a result of these findings, he asks the following question: Do students differ in terms of the points they earn in the course based on race and delivery environment? (Hint: Since you have learned about the importance of power, be sure to note and discuss observed power for each non-significant effect. Are there any possible Type I or II errors?)
