Required
a. Use the information from the high- and low-volume months to develop a cost-estimating equation for monthly labor costs.
b. Plot the data on a scatter diagram. Using the information from representative high- and low-volume months, use the high-low method to develop a cost-estimating equation for monthly labor costs.
c. What factors might have caused the difference in the equations developed for requirements (a) and (b)?
d. Adjust the equation developed in requirement (b) to incorporate the effect of an anticipated 7 percent increase in wages.
