Problem: Blackburn, Inc., an equipment manufacturer in Nashville, 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 0.048. Your desired performance is μ = 8.0 and σ = 0.045. What is the CpK of the Blackburn valve?
Round your answer to 3 decimal places; for example, 1.234.
