Question: A survey of \(n=200\) students from Big 10 universities found \(\bar{x}=23.5\) as the average age. If it is reasonable to assume that \(\sigma=6.8\), estimate the true mean age with \(90 \%\) confidence, and interpret the estimate. (Remember to state, with reason, whether the 1-Sample \(\mathrm{Z}\) or the 1-Sample \(\mathrm{t}\) procedure is appropriate.)
