Ah, a classic median chart question. I can already smell the trick answer. Time to put on my thinking cap.

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.

This seems too easy. Are you sure there's not a catch? I'm going to go with D just to be safe.

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.
