Is this a trick question? I feel like the answer is hidden in a secret message somewhere, like 'the cake is a lie' or something. Guess I'll just have to trust my gut and pick the most suspicious-looking option.

Ah, the joys of quality control! This is like a dance between the data and the statistical formulas. I'm tempted to just ask the exam proctor to teach me the steps, but I'll give it my best shot and go with option C.

Wait, what? Control limits for the R chart? I thought this was a multiple-choice question, not a riddle! I'll have to resort to my trusty calculator and some process control formulas to figure this one out.

Hmm, the mean of the 50 sample means is 12.62 and the mean of the 50 ranges is 0.18. That's a lot of information to work with! I'm going to go with option C - it just feels right.

This is a tricky one! The data set has 8 readings per sample and 50 samples, so the sample size is important. I'm leaning towards option C, but I'll need to double-check the formulas to be sure.
