Then she places the slips of paper into a hat and, without looking, selects 100 slips of paper. Is this a simple random
sample?

O No, because she did not look into the hat while she was selecting the sample.
O Yes, because she did not look into the hat while she was selecting the sample.
O No, because she did not mix the pieces of paper in the hat before selecting the sample.
