Option D seems plausible, but I'd need to do some calculations to be sure. Maybe I can borrow a calculator from the person next to me.

I think option D is correct, Grade A does have a higher sample Mean than Grade B.

Hmm, I'm not sure about option B. Paired T-test? That sounds like a fancy dance move, not a statistical analysis technique.

I think option C is correct. The data shows that Grade A has the lowest sample mean of the three samples.
