But what about using the individual and moving range? It could work too.

I think we should use x-bar and R. It fits the sample size.

I’m not clear on whether to use c or u charts for defects. I wish I had reviewed that section more thoroughly!

The p chart seems like a good option for defect proportions, but since we have counts, I’m leaning towards x-bar and R.

I think we should use the x-bar and R chart since we have a sample size of 85, but I'm not entirely sure.
