We randomly selected 26 TWU alum and asked them if they ever drink underage when in college? 16 said that they did. What is the 95% confidence interval for the true proportion of TWU alum who engaged in underaged drinking when in college? Enter your answers accurate to two decimal places. The correct interpretation of the confidence interval is that we are 95% confident that the interval contains the Select an answer 0 of Select an answer O TWU alum who engaged in underaged drinking when in college. Can we conclude that the proportion of all TWU alum who engaged in underaged drinking when in college is less than 0.84? Justify your answer. No; the entire interval agrees with this claim. Yes; the entire interval agrees with this claim. Yes; the entire interval does not agree with this claim. O No; the entire interval does not agree with this claim. O O O O

We randomly selected 26 TWU alum and asked them if they ever drank underage when in college. 16 said that they did. What is the 95% confidence interval for the true proportion of TWU alum who engaged in underaged drinking when in college? Enter your answers accurate to two decimal places.

( [____], [____] )

The correct interpretation of the confidence interval is that we are 95% confident that the interval contains the [Select an answer] of [Select an answer] TWU alum who engaged in underaged drinking when in college.

Can we conclude that the proportion of all TWU alum who engaged in underaged drinking when in college is less than 0.84? Justify your answer.

- No; the entire interval agrees with this claim.
- Yes; the entire interval agrees with this claim.
- Yes; the entire interval does not agree with this claim.
- No; the entire interval does not agree with this claim.

Choose the best response that discusses the validity of your results.

- Valid — the sampling methodology is good and there are at least 5 successes and 5 failures
- Questionable — there is likely to be some response bias
- Questionable — the sample size is less than 30
- Questionable — there is likely to be some nonresponse bias
