2#/Skip/ assess We randomly selected 23 TWU alum and asked them if they ever drink underage when in college? 7 said that they did. What is the 99% confidence interval for the true proportion of TWU alum who engaged in underaged drinking when in college?

We randomly selected 23 TWU alum and asked them if they ever drink underage when in college? 7 said
that they did. What is the 99% 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 but do not round
until the end of the problem.
The correct interpretation of the confidence interval is that we are 99% confident that the interval
contains the Select an answer v of Select an answer v 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 0.53? Justify your answer.
O No; the entire interval agrees with this claim.
O Yes; the entire interval does not agree with this claim.
O No; the entire interval does not agree with this claim.
O Yes; the entire interval agrees with this claim.
Choose the best response that discusses the validity of your results.
O Questionable - there is likely to be some response bias
O Questionable
the sample size is less than 30
O Questionable – there is likely to be some nonresponse bias
O Valid - the sampling methodology is good and there are at least 5 successes and 5 failures
