Edwards Engineering has a new 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 0.03. Your specifications are μ = 8.0 and σ = 0.04. Since variability exists, Edwards Engineering is willing to accept injection systems within ±1.5% of the mean.

a.    What is the UCL and LCL?
b.    What is the Cpk performance of the injection system?
