Question: 1. In an article in Quality Engineering, a research article presented individual measurement data on sand Compactibility, as follows:
For this data, the author reported that the lower and upper specifications for sand compactibility are 38 and 46, respectively. Use this information to calculate the C p and Cpk values.
2. Calculate the Cp and Cpk for a process characterized by the following data: Production specifications: 1.00 1 / 2 0.08 cm Process standard deviation: 0.005 cm Process distribution centered at 0.95 cm.
