tonys campaign for president of Michigan. Recall that a poll was taken before you joined the campaign. That poll surveyed 500 people and found that 53% of them intended to vote for tony

What does this poll result mean?

1. Sample proportion
2. Standard deviation
3. Margin of error
4. Confidence interval

Make sure you include your confidence level that she will get 50% or more of the vote

Please help and explain the confidence interval!! (lower,middle,upper,standard deviation)
