Hello, I've been trying to finish this all day and I'm about to run out of time. I would appreciate any help or advice to finish this. I made the diagram to represent the variables and I'm not 100 percent sure that I did it right but I don't know how to go about the mean difference. I'm supposed use hypothetical data (ie: just make up some numbers) and then create a scatter plot to represent the data to identify the regression line to put into an equation. I would be so grateful for any kind of help.
