PA5-2 (Algo) Estimating Cost Behavior Using Scattergraph, High-Low, and Least-Squares Regression Methods (LO 5-2,5-3, 5-4) Leslie Sporting Goods is a locally owned store that specializes in printing team jerseys. The majority of its business comes from orders for various local teams and organizations. While Leslie's prints everything from bowling team jerseys to fraternity/sorority apparel to special event shirts, summer league baseball and softball team jerseys are the company's biggest source of revenue. A portion of Leslie's operating information for the company's last year follows: Month January February March April May June July August September October November December Number of Jerseys Printed 220 215 245 555 700 615 460 350 320 250 205 200 Operating Cost $5,875 5,780 5,950 8,700 9,700 9,295 6,220 6,150 6,040 5,960 4,925 4,810 Required: 3. Using the high-low method, calculate the store's total fixed operating costs and variable operating cost per jersey. 4. Using the high-low method results, calculate the store's expected operating cost if it printed 475 jerseys. 5. Perform a least-squares regression analysis on Leslie's data. 6. Using the regression output, create a linear equation (y = a + bx) for estimating Leslie's operating costs. 7. Using the least-squares regression results, calculate the store's expected operating cost if it prints 630 jerseys. Complete this question by entering your answers in the tabs below.
