Linda Jones, an accountant for Golding, Inc., has decided to estimate the fixed and variable components associated with the company's repair activity. She has collected the following data for the past six months: Repair Hours Total Repair Costs 10 20 15 12 18 25 $ 800 1,100 900 900 1,050 1,250 Required: 1.

Estimate the fixed and variable components for the shipping costs using the high-low method. Using the cost formula, predict the total cost of shipping if 14 packages are shipped. 2. Estimate the fixed and variable components using the method of least squares. Using the cost formula, predict the total cost of shipping if 14 packages are shipped. 3. For the method of least squares, explain what the coefficient of determination tells us. Compute the coefficient of correlation
