b) Use employee identification numbers to randomly select 200 employees.
c) Select the first 200 employees to arrive at work Monday morning.
d) Survey the first 200 people to enter the company cafeteria.
Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! b, use employee id numbers
a doesn't cover the other 3 divisions. If all in a division were selected, and the division were randomly chosen, that would be a cluster sample, but the choice isn't that.
the first 200 employees to arrive excludes others without a valid reason, and the same for d.
