What is the Cpk performance of the injection system? 1 answer below »

Ettlie Engineering has a new catalyst injection system for your countertop production line. Your process engineering department has conducted experiments and determined that the mean is 8.01 grams with a standard deviation of .03. Your specifications arc:

µ = 8.0 and s = .04, which means an upper specification limit of 8.12 [= 8.0 + 3(.04)] and a lower specification limit of 7.88 [= 8.0 – 3(.04)].
