Answer: 770 voters in his district.
Explanation:
- Population is the largest group of individuals carrying some specific similar characteristics.
- A sample is a subset of population that is used to represents the entire population.
Given : A state representative wants to know how voters in his district feel about enacting a statewide smoking ban in all enclosed public places, including bars and restaurants, as well as several other current statewide issues.

Thus , the sample is : 770 voters in his district.
