5. The HR department of a large company wants to determine how often to bring
representatives from the financial firm managing employee pensions on site to meet with
individuals about their retirement plans. In order to determine level of interest, they
decide to survey employees. Suppose they group employees by age categories (e.g.,
under 30; 30 – under 45; 45 – under 60, 60 or older) and randomly select 50 individuals
from each category. This sampling plan is called
A. Simple Random Sampling
B. Stratified Sampling
C. Cluster Sampling
D. Systematic Sampling
E. Convenience Sampling
3.3. Analyze the sampling method.
