Subgroups were definitely used in this analysis.

I think the mean of the moving range is actually higher.
MA

The process is assumed to be Normal, that's true.

Wait, are most values really outside tolerance? That sounds off.
TE

Definitely agree, the process seems out of control.

I have a feeling that E is definitely untrue since we usually look for most values within tolerance in capability analyses.
EU

I'm leaning towards C being untrue because I thought we discussed how to identify if a process is in control during our last review.

I remember a practice question where we had to determine if the mean was correct, so I feel like B could be misleading.

I think option A might be true, but I'm not completely sure if the process can be assumed to be Normal without more data.

This is a good opportunity to demonstrate my understanding of capability analysis. I'm confident I can nail this question.

Alright, I think I've got a handle on this. Time to put my process control knowledge to the test and select the untrue statements.

Okay, I've got a strategy for this. I'll methodically go through each statement and check it against the capability analysis information provided.

Hmm, I'm a bit unsure about this one. I'll need to think through the assumptions and calculations step-by-step to make sure I identify the correct untrue statements.

This looks like a tricky question. I'll need to carefully review the capability analysis details to determine which statements are untrue.
VE

D must be the correct answer. Using subgroups is a fundamental part of capability analysis. How could they mess that up?

Haha, this exam is a joke. They're trying to catch us out with these trick questions. I bet the real answer is that they're all true statements!

I agree, the Mean of the process moving range is not 1.78.

No way, the process is definitely out of control.
BE

I think the answer is that they're all true statements.

E seems off to me. If the majority of the values were outside the tolerance, the process would not be normally distributed. That's just basic statistics.
LA

User 3: E) Majority of the dimensional values are outside of the tolerance than within
PE

User 2: B) The Mean of the process moving range is 1.78
FI

User 1: A) The process is properly assumed to be a Normal process
FE
Felix

I believe statement E is also untrue, as most values are within tolerance.
AL

I agree with Karrie, the process seems to be in control.
KA

I think the statement C is untrue.
VI
Vinnie

I think B is definitely not true. The mean of the process moving range should be 1.128, not 1.78. Did they even look at the data?
DA
Dacia

User 2: Yeah, they must have made a mistake in their analysis.
LU

User 1: I agree, the mean of the process moving range is definitely not 1.78.
