A. 0.33

B. 0.56

C. 1.11

D. 3.33

Process Capability Index:

Process capability index is a measure of the long-term performance level of a process that is under statistical control. The information required to calculate the process capability index of a process are the design specification range and the mean and the standard deviation of the process.

Answer and Explanation:

The answer is B. 0.56.

In this problem, the USL = 10.5, the LSL = 9.5, the mean {eq}\bar{x} {/eq} = 10, and the standard deviation {eq}\sigma {/eq}...
