An employer asks the survey question “How much money do you spend on gasoline per week to get to work?” of her employees that drive to work. Which best describes why she chose to only ask the employees that drive to work rather than all of her employees?
Answer
A
All employees were adequately represented by the sample that drives to work.
B
The employees that drive to work adequately represented the sample.
C
The employees that drive to work were the target of her survey.
D
All employees were too difficult to survey because the group was too large.
Explanation
The survey asks about gasoline spending to get to work, so the relevant group is employees who drive to work. They are the target of the survey because they can provide meaningful answers about that expense; employees who do not drive are not needed for this question.
