6. A certain town has 25,000 families. The average number of children per family is 3 , with an SD of 0.60.20% of the families have not children at all. The distribution is normal. (a) a simple random sample of 900 families is chosen. 18% of 900 families has not children. Is this reasonable. (b) Out of 900 families, the average number of children per family is 2.9. Is this reasonable?
