The professor who gave the midterm wanted to get an idea of the average class grade on the midterm for course reevaluation. Here, one would determine x¯=74.8 (try it yourself before proceeding).  This would be our weighted mean.

For this discussion, I want you to come up with your own weighted mean problem related to your major and solve it. First, create a labeled table of values (use mine as a reference), then, provide the sample size, and lastly, determine the weighted mean. Why would someone want to know the weighted mean in your example from your major?
