Answer

# Answer: A. Assign each employee consecutive whole numbers starting with 1. Then, choose employees whose assigned numbers are even. # Explanation: ## Step1: Define stratified sampling Stratified sampling divides population into subgroups. ## Step2: Analyze option A Assigning numbers and choosing evens is systematic. ## Step3: Analyze option B Organizing by job - title and random sampling is stratified, not systematic. ## Step4: Analyze option C Organizing by seniority and sampling long - term workers is biased. ## Step5: Analyze option D Sampling only cashiers is biased. ## Step6: Analyze option E Incomplete option description, but sampling only one job - title group is biased.
