Final Answer :
E
Explanation :
The Cpk index calculates the number of standard deviations between the mean and the nearest specification limit. A value of 2 corresponds to a process that can produce Six Sigma quality (3.4 defects per million) as it indicates a distance of 6 standard deviations between the mean and the nearest specification limit (2 x 3 = 6). Therefore, the best choice is E.
