Responses

all employees who have worked in the company for 5 years or more

a group with one member from each department
a group with one member from each department

all 624 female employees in the company
all 624 female employees in the company

400 randomly chosen employees from the list of all employees
400 randomly chosen employees from the list of all employees

Answer 1

400 randomly chosen employees from the list of all employees.

Reason: a random sample from the full employee list is most likely to be representative of the whole workforce and minimize selection bias. The other options systematically exclude or under/overrepresent groups (long‑tenured only, only females, or one person per department regardless of department size).
