Question

In a recent survey of 974 voters, 724 indicated that they were in favor of a new city park, while the other 250 voters said that they were opposed.
Using this survey as a basis, if 40,000 citizens vote next week, how many are likely to be opposed to the new park? Round to the nearest whole number.

Answer 1

10, 267

the fraction of voters opposed from the survey = $\frac{250}{974}$

Assuming this fraction as a basis then the predicted number against will be

40, 000 × $\frac{250}{974}$ = 10, 267 ( nearest while number )
