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 (mu) of 12.00 and a standard deviation (sigma) of 0.04. Your desired performance is mu = 12.00 +/- 3 standard deviations, where sigma is 0.020.
