I need guidance on figuring out a linear regression model from a dataset

[James.wilson]

Hello, I'm completely stuck on this. If anyone could guide me in the right direction for this linear regression model it would be very appreciated!

Did you put any data into one of the packages and get results? What were they?

EDIT: By the way, thank you for including a complete statement of the problem. I don't like the wording of the problem, but that is not YOUR problem, nor is this my chosen field.
