During elections, such as the presidential election, election forecasters will typically use exit polls to try to predict the outcome of the presidential election. We might hear that a candidate's lead is "outside the margin of error" or there is a "statistical tie". What does this mean?

In your answer, be sure to include the following:

1. What is a confidence interval?
2. What is margin of error?
3. How do confidence intervals help us estimate a population parameters?
4. In a 95% confidence interval, what does the 95% refer to?
5. Provide an example to explain what a statistical tie is.
6. Provide an example to explain what a means to have a lead outside the margin of error.
7. Why is it dangerous to make predictions "within the margin of error"?
