The Pacific Fruit Company has designed its packaging process for boxes to hold a net weight (nominal value) of 9.0 oz of raisins with tolerances of plus or minus 0.5 oz. Given a process mean of 9.00, an average range of 0.57 and a UCL of 1.21 and a LCL of 0, compute the process capability ratio and index.

Cp = _____ (Round your answer to
2 decimal places, the tolerance is +/-0.05) Which of the following statements is true concerning the process capability ratio and index? - the process is capable and centered - the process is capable, but off center - the process is off center and incapable - the process is centered, but incapable HINT my professor gave - Here's the hint: use R-bar and A2 where A2 = 0.58 for this problem. This is the formula to work with: |
