What is the advantage of selecting a stratified random sample, with location as strata, instead of a simple random sample?The stratified sample assures the most random selection from among all selection methods.AThe stratified sample assures that the opinions of employees from both locations will be represented.BThe stratified sample will be less expensive to implement than a simple random sample and will save money over time.CThe stratified sample assures employees that store hours will not be extended until their opinions are recorded.DThere is no real advantage to stratifying because a simple random sample is always the best.
