1. If the specification is such that no washer should be greater than 2.4 millimeters, assuming that the thicknesses are distributed normally, what fraction of the output is expected to be greater than this thickness?

2. What if there is an upper and lower specification, where the upper thickness limit is 2.4 and the lower thickness limit 1.4, what fraction of the output is expected to be out of tolerance?

3. What is the C_pk for the process?

4. What would be the C_pk for the process if it were centered (assume the process standard deviation is the same)?

5. What percentage of output would be expected to be out of tolerance if the process were centered?
