Hi, I have a question about this problem. I didn't quite understand the answers. I thought a) would be A, and for b, I wasn't sure.

Did you check average of each trial and check which average is closer to the accurate answer.
For precise check which readings are very close to each other. C student readings are not precise at all. Now select from student A and B.

Oh, ok, that makes sense now. I think I wasn't averaging each trial; therefore, I mistakenly got the wrong answer
