Question

A local library manager randomly surveys 80 patrons about the type of book they borrow when they visit the library. The manager finds that 3 patrons borrow novels. If the local library has 345 patrons, approximately how many of them borrow novels when they visit the library? Round your answer to the nearest whole number.

Answer 1

Estimated proportion = 3/80 = 0.0375.
Estimated number = 0.0375 × 345 = 12.9375 ≈ 13.

So about 13 patrons.
