Plz me : (
a certain store has 3,000 employees working at its main location in a city and 100 employees working at a smaller location outside the city. the store manager will select a sample of 50 employees from all the employees to ask their opinions about extending store hours during the holidays. 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.
a
the stratified sample assures that the opinions of employees from both locations will be represented.
b
the stratified sample will be less expensive to implement than a simple random sample and will save money over time.
c
the stratified sample assures employees that store hours will not be extended until their opinions are recorded.
d
there is no real advantage to stratifying because a simple random sample is always the best.
