Given the data for Corell Transport in the previous problem, estimate the linear model and compare it with the non-linear, quadratic model.

Previous problem

Corell Transport hauls heavy cargo between several major cities across the country. Rising fuel costs have caused a concern within upper management over future profit levels. Access the file CORELL TRANSPORT containing data for miles driven in thousands and average costs in hundreds of dollars. Using your preferred software, estimate the average cost curve for Corell's operations. Keep in mind that the average cost curve is a ∪-shaped quadratic of the general form AC = f(Q, Q2).
