Using this Homework 1.pdf, I need help figuring out how to set up #7.

Use the data from 2013 and 2014 to determine whether average monthly sales for the BMW 5 series exceed 4,000 vehicles? Use 1% significance. I am referencing the worksheet in your files under University of North Carolina Business MBA 715, Homework #1 Automobile Sales - Confidence Intervals and Hypothesis Tests. When I googled it, your site was the first to show it had that worksheet so I thought I would join to see if I could understand. Does that help or do you still need more information?
