The Professor's Response
I was working on questions from 7.3 Now You Try It, from STATSprofessor and I noticed that the answer for number 3 was "195 children". But when I got my answer I got 195..4..... and I rounded up to 196, because as you said in your videos, one should round up when we are talking about people or things, in this case children. Am I correct to round up to 196, or is the answer sheet correct?
