---### Confidence Interval Analysis for Underage Drinking Study#### QuestionWe randomly selected 29 TWU alumni and asked them if they ever drank underage while in college. 12 said that they did. What is the 90% confidence interval for the true proportion of TWU alumni who engaged in underage drinking while in college? Enter your answers accurate to two decimal places but do not round until the end of the problem.\[ ( \_\_\_\_\_ , \_\_\_\_\_ ) \]#### InterpretationThe correct interpretation of the confidence interval is that we are 90% confident that the interval contains the \[ \_\_\_\_\_\_\_\_ \] of \[ \_\_\_\_\_\_\_\_\_\_\_ \] TWU alumni who engaged in underage drinking while in college.#### ConclusionCan we conclude that the proportion of all TWU alumni who engaged in underage drinking while in college is less than 0.57? Justify your answer.- [ ] Yes; the entire interval does not agree with this claim.- [ ] No; the entire interval agrees with this claim.- [ ] No; the entire interval does not agree with this claim.- [ ] Yes; the entire interval agrees with this claim.#### Validity of ResultsChoose the best response that discusses the validity of your results.- [ ] Questionable — there is likely to be some nonresponse bias.- [ ] Questionable — there is likely to be some response bias.- [ ] Questionable — the sample size is less than 30.- [ ] Valid — the sampling methodology is good and there are at least 5 successes and 5 failures.[Submit Question]---This passage is designed to help students understand how to construct, interpret, and draw conclusions from confidence intervals in statistical studies, specifically in surveys about behaviors such as underage drinking. This includes determining the validity of the data collected based on sample size and potential biases.

construct a confidence interval for this data. You should construct a 95% confidence interval for this data. How you do this will depend on whether your data is summarized using a mean or proportions. If you have categorical data, you will have to pick one of the categories and focus on a confidence interval for the proportion for that category, and you only need to do one for that one category. Please show the parts of your equation (point estimate, Z or T, and standard error) in addition to your final result.
Data are used either to test a hypothesis or to construct a confidence interval, but not both. Explain.
