This question feels similar to one we practiced, where we had to find limits using sample means. I think the answer might be B.

I think the control limits are based on the mean and the range, but I can't recall the exact formula we used.

I remember we calculated control limits for median charts in class, but I'm not sure how to apply the mean and range here.

This seems straightforward enough. I just need to plug the values into the right formulas and do the math. I'm feeling good about being able to solve this one.

Let's see, the question gives us the mean of the 50 sample means and the mean of the 50 ranges. I think I can use those values to find the control limits for the median chart.

But the mean of the 50 sample means is 12.62, so I think A) makes more sense.

Did anyone else notice the sample size is a bit odd? 50 samples with 8 readings each? Feels like there might be a trick question here.

Wait, why are we looking at the mean of the ranges? Shouldn't we be focusing on the sample means? I'm leaning towards A.
