Question

natasha wants to find out if the neighborhood supports lowering the speed limit on the street in front of her... which is a valid sample for the survey? students in natasha’s social studies class, parents who live in a town 15 miles away from natasha’s school, the first 5 drivers who drive past natasha’s school one morning, thirty residents who live within a 2-miles radius of natasha’s school

Explanation:

To determine a valid sample for surveying if the neighborhood supports lowering the speed limit, the sample should represent the neighborhood residents.

• "students in Natasha’s social studies class" are not neighborhood residents.
• "parents who live in a town 15 miles away" are not in the neighborhood.
• "the first 5 drivers who drive past" is a small, non - representative sample.
• "thirty residents who live within a 2 - miles radius of Natasha’s school" (the neighborhood) is a representative sample of the target population (neighborhood residents).

Answer:

thirty residents who live within a 2 - miles radius of Natasha’s school
