Answer:
A. The stratified sample assures that the opinions of employees from both locations will be represented.
Explanation:
This option is correct, because it ensures that the results of the survey represent employees' opinions from both rural and urban locations. Gathering employees' opinions from both locations will furthermore ensure that any policy dependent on the results of this survey not only represent urban employees' interests (as they are the majority), but also the rural employees' interests.
Option B is incorrect as a stratified sample will be <em>more </em>expensive to implement than a simple random sample and will <em>not necessarily help to</em> save money over time.
Option C does not apply as it is simply an assumption that has no evidence to support it.
Option D is incorrect as a stratified sample in this case is better than a random sample in generating results that are more representative of the store's employees from both locations.
