I could use help with the following problem. 19.1A Thank you!

Castner Corporation is considering implementation of a JIT inventory system. The company's industrial engineer recently conducted a study to determine the average number of days spent in each activity of the production process. The following table summarizes her findings: Production Activity Number of Days Inspecting materials 3 Storing materials 17 Moving materials into production 3 Setting up production equipment 2 Cutting materials 6 Bending materials 5 Assembling finished products 9 Painting finished products Instructions Identify Castner's value-added production activities. Identify Castner's non-value-added production activities. Calculate Castner's total cycle time. Determine Castner's manufacturing efficiency ratio. Which of the above activities might be reduced or eliminated if Castner implemented a JIT system? What ethical issues might be related to eliminating some of the non-value-added activities
