1. The administration of XYZ Company is interested in learning about the types of
wellness programs that would interest its employees. Suppose that there are five
categories of employees (administration, faculty, professional staff, clerical and
maintenance) and the university decides to randomly select ten individuals from each
category. This sampling plan is called

B. Stratified Sampling
C. Cluster Sampling
D. Systematic Sampling
E. Convenience Sampling

2. The administration of XYZ company is interested in learning about the types of
wellness programs that would interest its employees. Suppose that the university
randomly selects individuals (administration, faculty, professional staff, clerical and maintenance) who work at different locations (e.g., Knoxville, Harrogate). This sampling plan is called

3.MGS, a regional shoe chain, has recently launched an online store. Sales via the
Internet have been sluggish compared to their brick and mortar stores, and management
wants to survey its regular customers about potential concerns regarding the security of
online transactions. Suppose that MGS’s regular customers belong to a rewards program
and have a customer rewards ID number. MGS decides to randomly select 100 numbers.

4. Management at a large multinational corporation would like to survey its employees
about the level of interest in combining flexible work schedules with telecommuting from
home. Each employee has an ID number, and the administration plans to randomly select
250 numbers. This sampling plan is called

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.
