Question 3 • Pre-Algebra B

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

Explanation

The department needs opinions from the community, so the people surveyed should represent Hamden residents broadly. A random sample of 10% of all taxpayers is the most suitable choice because it covers a broad group in the community. Students, car salespersons, and construction workers are narrower groups and may not reflect the community as a whole.
