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 12.00 and a standard deviation (σ?) of 0.05. Your desired performance is μ = 12.00 ± 3 standard? deviations, where σ = 0.040. For the given? information, the process capability index (Cpk?) = ________ ?(round your response to three decimal? places).
