A quality engineer is assessing the capability of a process. He took a sample of the production line for the inner tubes, which yileded an average of 61 psi with a satndard deviation of 2 psi. The specification calls for the acceptance range to be from 55 psi to 65 psi. What is the Cpk of this line?

The Cpk of this line is 0.6667.

Step-by-step explanation:

Cpk:

In a process with mean , standard deviation , upper limit U and lower limit M, the CPK is of:

Average of 61 psi with a standard deviation of 2 psi.

This means that

The specification calls for the acceptance range to be from 55 psi to 65 psi.

This means that .

Cpk

The minimum of these values is 0.6667, so the Cpk of this line is 0.6667.

x = 25/2304
