Question 2 • Grade 7 Mathematics

Hamden city’s police department needs to choose whether to build a new addition to the police station or to buy new squad cars. Which sampling option might they choose to survey the community?

Answer
A
a random sample of 10 percent of Hamden students
B
a random sample of 10 percent of all the people in the construction business
C
a random sample of 10 percent of all car salespersons
D
a random sample of 10 percent of all taxpayers

Explanation

The department wants to learn what the Hamden community thinks, so its sample should represent people who live in and contribute to the community. A random sample of 10 percent of all taxpayers is more representative than surveying only students, construction workers, or car salespeople, since those groups have particular characteristics or interests.
