Explanation:

⚡ Using what you learned: Population vs. Sample

Step 1: Define the Target Population

The target population is the entire group of individuals that researchers want to draw conclusions about. In this scenario, the surveyors want to predict the outcome of the upcoming city council election in Raleigh.

The individuals eligible to decide this election are the registered voters of the city. Therefore, the group the surveyors are ultimately interested in generalizing their findings to is all registered voters in Raleigh.

Step 2: Distinguish Population from Sample

• All registered voters in Raleigh (7,000 people): This is the entire group of interest (the population).
• The 300 voters surveyed: This is the subset of the population actually selected to gather data (the sample).
• All citizens of Raleigh: This includes non-voters (such as children or unregistered residents) who cannot vote in the election, so they are not the target group.
• All registered voters with telephones in Raleigh: While the survey was conducted by telephone (introducing a potential sampling bias), the surveyors' intended group of interest remains all registered voters, not just those with phones.

Answer:

All registered voters in Raleigh
