Linda boardman, inc., an equipment manufacturer in boston, has submitted a sample cutoff valve to improve your manufacturing process. your process engineering department has conducted experiments and found that the valve has a mean (μ) of 8.00 and a standard deviation (σ) of .04. your desired performance is μ = 8.0 ±3σ, where σ = .045. a. what is the upper specification = and the lower specification = b. what is the cpk of the boardman valve? c. is the process centered and will it produce within the specified tolerance?
