Which of the following is not a true statement about the resulting stratified sample? a. It is more susceptible to bias than would be a simple random sample.
b. It is easier and more cost effective than a simple random sample.
c. It gives comparative information that a simple random sample wouldnâ€™t give.
d. It recognizes that opinions of heads of household in rural NY communities may differ from those in urban communities.
