Key Concepts
- Applying Sample Proportions to Predict Elections: Polls estimate voter preferences, which can be scaled up to larger voting populations.
- Computing Vote Differences: Using predicted vote counts to determine expected election outcomes.
Skills Covered
- Using poll results to estimate election outcomes.
- Calculating expected vote differences based on poll projections.
Example Problems
- A poll of 500 voters finds that 55% plan to vote for Candidate A. Predict how many votes Candidate A will receive if 100,000 people vote.
- A survey suggests that Candidate X will get 48% of the votes, while Candidate Y will get 52%. If 50,000 people vote, by how many votes is Candidate Y expected to win?
