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 sample population should be representative of the entire student body. Students staying after school, in the library at lunch, or in the student section at a football game may have specific characteristics or interests that don't reflect all students. However, students in the main hallway between classes are more likely to be a diverse cross - section of the student population.

Answer:

Every tenth student in the main hallway between class.
