Actually, the correct answer is D) 1.25. The Cpk value indicates how well a process can meet the specifications, and in this case, it exceeds 1.00.

This question is making my head spin. I need to remember the Cpk formula - something about standard deviations and spec limits. You know what, I'm just going to go with D) 1.25 and hope the examiner has a sense of humor.

Yeah, it's a bit confusing. I'm going with D) 1.25 and hoping for the best.

Hey, isn't Cpk just another way of saying 'Can't Possibly Know'? I'm going to go with B) 0.75 and hope for the best. At least it's not as bad as E) 'Completely Perplexed'.

I'm not sure, but I think the Cpk value should be higher than 1.00 for a good process capability.

Okay, let's break this down. If the process average is 98 and the spread is 16, that means the process is well within the spec limits. I'd say the Cpk has got to be 1.25. Nailed it!

Actually, the Cpk would be 1.00. The process is well within the spec limits.

I agree with you, the Cpk would be 0.75 in this case.

I think it's actually 0.75. The process is not quite hitting the upper spec limit.

Wait, wasn't Cpk something to do with how well your process is centering between the spec limits? I'm pretty sure the answer is C) 1.00. Gotta love those statistics questions, am I right?

Hmm, let me think about this. The spread is 16 units, and the spec limits are 115 and 90 units. I think that's going to give us a Cpk value of around 1.00. Sounds about right to me.

Yes, the Cpk value of 1.00 seems to make sense given the average, spread, and spec limits.

I think you're right, the Cpk value is likely 1.00 based on the given information.
