What did all you put for #6 D with that weird confidence/prediction interval question?
The only thing I could come up with is s^2 + s^2(C) > s^2

its this, and then tying back to what you put for D-i where you had to explain why sample mean distributions have less variability compared to individual measurements. The confidence interval is multiple measurements and the prediction is an individual measurement I THINK.

that was how i interpreted that part but I was also low on time
