Question 13 (10 points) Mark's Ceramics spent $10,000 on a new kiln last year in the belief that it would cut annual energy usage 25% over the old kiln. This kiln is an oven that turns "greenware" into finished pottery. Mark is concerned that the new kiln requires extra labor hours for its operation. Mark wants to check the energy savings of the new oven, and also to look over other measures of their productivity to see if the change really was beneficial. Mark has the following data to work with: a. Calculate the multi-factor productivity for each year. b. Based on the productivity, do you think the modifications were beneficial? Why or why not?
