Question 2 (5 points) (08.01)
Sam wants to know how many families in his neighborhood plan to attend the
neighborhood cookout. He puts all 100 of the neighborhood addresses in a hat and
draws a random sample of 25 addresses. He then asks those families if they plan to
attend the cookout. He finds that 15% of the families plan to attend the cookout. He
claims that 15% of the neighborhood families would be expected to attend the
cookout. Is this a valid inference? (5 points)
