Cablesplice, Inc. manufactures coaxial cable. The process consists of five steps: making the conducting wire, adding insulation, adding sheathing, irradiation, and finishing. Units of production are measured in meters. In 800 meters of cable, 55 defects were found in the wire and 37 defects were found in the insulation. In 500 meters of cable, 12 defects were found in the sheathing. Irradiation and finishing had 6 and 15 defects, respectively, in 600 meters of cable. a) Calculate the DPU and throughput yield for each of the five process steps. b) Calculate the rolled throughput yield of the entire process.
