Please determine the Cpk, FTY (First Time yield) and the DPU (Defects Per Unit) for each process. b. If all of these coating were applied to a single surface, show the total Cpk,FTY, and DPU TIP: Neither the Specifications nor the Mean and Sigma for each process has any units given. Do not assume that the numbers represent any particular physical attribute
