Question

staff from the school newspaper is taking a poll to find out how students in the school are going to vote in the upcoming election for class president. which group would best represent a sample population? every tenth student staying after school. every tenth student in the library at lunch. every tenth student in the main hallway between class. every tenth student in the student section at the school football game.

Explanation:

A representative sample should reflect the entire student body, not a narrow subgroup. Students staying after school, in the library at lunch, or at a football game are specific subsets (e.g., those with after-school commitments, library users, sports fans). Students in the main hallway between classes include a diverse cross-section of all students, as most students traverse hallways between classes regardless of their activities or groups.

Answer:

C. Every tenth student in the main hallway between class.
