Choose three of the questions below to answer.
1. You want to estimate the average age of users on a popular social media app. What would a 0% CI be? What would a 100% CI be?
2. Explain in your own words why a 95% confidence interval would be narrower when the sample size changes (even if it is still 95%).
3. Give an example of one situation in which we would want a 99% confidence interval instead of a 95% confidence interval.
Give an example of one situation in which we would be ok with a 70% confidence interval instead of a 95% confidence interval.
4. Explain in your own words what a confidence interval is and what it is estimating. Pretend you are talking to someone who has not taken a statistics class and avoid any vocabulary words that they would not know.
5. Explain in your own words the difference between point estimates and confidence interval estimates. Explain which estimate is more accurate.
