Question 1128098: A company wants to determine the level of interest among its employees for an annual summer picnic.The company wants to survey 200 employees.
What is the best way to randomly choose these 200 employees?


a) Choose 50 people from 4 of the 7 divisions at the company.
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.

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.
