The president of the student council wants to survey the student population. She decides to take a random sample of 100 students. She puts every student’s name on a rectangular slip of paper, each with the same length and width. Then she places the slips of paper into a hat and, without looking, selects 100 slips of paper. Is this a simple random sample?

C
Yes, because she did not look into the hat while she was selecting the sample.
D
