I'm not sure, but I think the control limits should be within a certain range based on the data provided.

Ugh, control charts. I always get them mixed up with run charts. Maybe I should just guess and hope for the best?

I agree with Benton, the mean of the 50 sample means is 12.62 so it makes sense.

Okay, this is a classic control chart problem. I'm going to have to break out my trusty Statistical Process Control handbook for this one.

I'm feeling confident about A. The mean of the sample means is 12.62, so the control limits should be pretty close to that, right?

D. None of the above? Really? That's a bold move. I'm going to have to think this one through a little more carefully.
