Wait, is this a trick question? What kind of process has an average of 94 and a spread of 22? Seems a bit off to me. I'll go with C) 1.84, just in case.

I'm not sure about this one, but I'll go with D) 2.12 just to be safe.

I think it's B) 1.27, the calculation checks out.

I think Mayra might be right, because the Cpk value indicates how well a process can meet the specifications.

I believe the correct answer is D) 2.12 because the process is well within the specification limits and has a high Cpk value.

I'm not sure, but I think the correct answer is C) 1.84 because the Cpk value should be greater than 1 for a process to be considered capable.

Hold up, I thought Cpk was all about finding the perfect balance. Clearly, the answer is D) 2.12. Nailed it!

I'm pretty sure the formula for Cpk involves the spread and the specification limits. Gotta be C) 1.84, right?

Hmm, let's see... the Cpk should be centered around the average, so B) 1.27 seems like the way to go here.
