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 455 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 600 jerseys.
