1) Use the previous relative frequency distribution to obtain the percentage of U.S. households that are at least size 3 and at most size 5?
2) Use your answer from part a) to estimate the fraction of area under the corresponding normal curve that lies between at least size 3 and at most size 5?
3) Use your answer from part a) to estimate the probability of choosing a size between at least size 3 and at most size 5?
