In 1997 Fuller and coworkers at Texas A&M University estimated the operating costs of cotton gin plants of various sizes. The operating costs of the next to the smallest plant is shown in the following table. x 2000 4000 6000 8000 10000 12000 y 163,200 230,480 301,500 376,160 454,400 536,400 Here x is the annual number of bales produced, and y is the dollar total cost. (Use 4 decimal places in your answer.)A. Determine the best fitting line using least squares. Also determine the square of the correlation coefficient.The best fitting line is C(x) = .The square of the correlation coefficient is r2 = .B. The study noted that revenue was $63.25 per bale. At what level of production will this plant break even?The revenue equation is R(x) = The profit equation is P(x) = The production will break even when bales are produced.C. What are the profits or losses when production is 3000 bales? 4000 bales? (Round to the nearest cent.)When…
