A Lawn care company is trying to predict the number of hours it takes to mow mow grass and care for larger industrial and commercial clients. They've built one regression model that only uses the number of square feet they need to care for (r2 = 0.72), and another regression model that includes square feet to service, number of trees on the property, and the number of disconnected pieces of lawn that need to be mowed (r2 = .78). The model is built based on n = 50 current properties they service. Perform the test to see if the second model is meaningfully better than the first. Make sure to show all steps. Instead of calculating the test statistic, instead show the formula for finding Fas well as all the values that should go into that equation. Then, perform the test as if F = 7.2.
