I got 1.27 too, but I double-checked just in case!

Cpk is calculated using the formula, right?

I think the answer is A, but I need to double-check my calculations. The process average is below the midpoint of the specs, right?

I feel like I might be overthinking this. The spread is 22 units, but I can't recall how that impacts the calculation.

This seems similar to a practice question we did last week. I think the average being closer to the lower limit affects the Cpk value.

I remember we calculated Cpk in class, but I'm not sure if I got the formula right for this one.

Alright, time to put my process improvement skills to the test. I just need to plug the numbers into the right formula and I should be good to go.

No problem, I've got this. Cpk is all about how well the process is centered and how tight the variation is compared to the spec limits. I'll work it out.

Okay, I think I can handle this. The key is to calculate the Cpk based on the process average, spread, and specification limits.

Hmm, this looks like a question on process capability. I'll need to remember the Cpk formula and plug in the given values.

Wait, what's Cpk again? I'm a little fuzzy on the details of that metric. Let me think this through step-by-step.

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

Maricela

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?

Pamella

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