According to the question
In Six Sigma methodology, Cp (Process Capability Index) and Cpk (Process Capability Index with respect to the process center) are used to assess the capability of a process to meet customer specifications.
These indices are calculated using the following formulas:
Cp = (USL – LSL) / (6 Standard Deviation)
Cpk = min(USL – Mean) / (3 Standard Deviation), (Mean – LSL) / (3 * Standard Deviation))
USL is the upper specification limit
LSL is the lower specification limit, and the Mean is the process mean or average.
In a Six Sigma process, you typically aim for a Cp of 2.0 and a Cpk of 2.0. This level of capability means that the process is capable of producing products or services that are well within customer specifications, with a very low defect rate.
So, the correct answer to your question is:
d) Cp=2.0 and Cpk=2.0
