9. How does the cost of production report for the second department in the production process differ from the cost of production report from the first department in the process? 10. If the average cost method is used, and an error was made in estimating the percentage of materials in the ending work in process inventory. What would be the effect of this error on equivalent units of production? What would be the effect on the cost of the goods transferred out for the period?' Please answer both questions, thank you in advance! 9.
