question 128

Multiple Choice

The process capability measures C_p and C_pk differ because:

• B) C_p values above 1 indicate a capable process, while C_pk values above 2 indicate a capable process.
• C) They do not differ: both are identical.
• D) C_p values for a given process will always be greater than or equal to C_pk values.
• E) Both A and D are correct.
