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?

b)Use employee identification numbers to randomly select 200 employees.

Step-by-step explanation:

Complete question is :

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.

explanation:

'a' doesn't cover the other 3 divisions. On the off chance that all in a division were chosen, and the division were arbitrarily picked, that would be a cluster sample, however the decision isn't that.  

the initial 200 representatives to show up excludes others without a substantial explanation, and the same for d.

Also,If we surveyed the first 200 people to enter the cafeteria, then the result might be biased because the type of person to enter the cafeteria early might be the type of person to want a picnic more. Kind of like if you wanted to determine the level of interest a school has of making math class last for twice as long, you wouldn't want to just ask the first 200 people that turn in their math test.

thus,  randomly selecting 200 employee ID numbers would probably be the best method.
