Operator 1: "I've been keeping an eye on my operating room instruments. I feel as though our energy consumption is becoming less efficient." The Coating Department had no beginning or ending inventories for any month during the study period. The following data from the cost of production report are made available: Pix Paper Inc. Schedule of Costs for Six months b. Interpret your table results. Operator 1 believes that energy consumption is becoming expect to see the conversion rate per pound Operator 2 believes that there are validated. The stable cost of the paper stock per output pound also suggests that the yields are remaining stable. : for the six months. If the energy efficiency were. , then there would be less materials transferred out per pound of inputs over time. The yield has Operator 3 is concerned about coating costs. The coating cost per output pound over time. Thus, it can be concluded that the coating efficiency is over time. coating is being spread on the paper stock. coating is being spread on the paper stock. , it would take more energy per pound of output over time. Thus, we would over the six-month period. Thus, Operator 2 's hypothesis
