Question

the mayor wants to know how the people of the city feel about a bottle tax. she sends her staff to a randomly selected block in each of the city’s election districts. the staff members interview all the residents on the block that are home that day. what is the population?
○ all the people in the city
○ all the people who live on the block
○ all the people who live on the block and are home that day

Explanation:

The population in a survey context is the entire group about which we want to gather information. Here, the mayor wants to know how the people of the city feel about the bottle tax, so the population should be all the people in the city. The other options refer to samples (either the block's residents or those home on the block) rather than the entire population of interest.

Answer:

A. all the people in the city
