Question

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

A college professor would like to estimate the proportion of students who pull an "all-nighter," meaning they study all night for an upcoming exam. She selects a random sample of 100 students from her large college and finds that the 99% confidence interval for the true proportion of students who pull an all-nighter is 0.48 to 0.62. Which of these statements is a correct interpretation of the confidence level? O Approximately 99% of all students have pulled an all-nighter. O There is a 99% probability that the true proportion of all students who pull an all-nighter is between 0.48 and 0.62. If many random samples of size 100 are selected from all students at this college, approximately 99% of the intervals would capture the true proportion who pull an all-nighter. C Approximately 99% of the sample proportions of students who pull an all-nighter, based on random samples of size 100 from the population of all students at this college, will fall between 0.48 and 0.62.
