Question 1
The process capability measures C
p and C
pk differ because
◦ C
p values above 1 indicate a capable process, C
pk values above 2 indicate a capable process.
◦ C
pk values for a given process will always be greater than C
p values.
◦ only one ensures the process mean is centered within the limits.
◦ C
p values for a given process will always be greater than or equal to C
pk values.
◦ both are identical.
Question 2
A C
p of 1.33 indicates how many sigma limits?
◦ 1.33
◦ 2
◦ 3
◦ 1
◦ 4
