QuestionEat your cereal: Boxes of cereal are labeled as containing 14 ounces. Following are the weights, in ounces, of a sample of 12 boxes. It is reasonable to assume that the population is approximately normal. \begin{tabular}{llllll} \hline 13.01 & 14.96 & 13.10 & 13.11 & 13.09 & 13.01 \\ 13.14 & 14.96 & 13.04 & 13.03 & 13.10 & 13.11 \\ \hline \end{tabular} Send data to Excel
Part: 0/20 / 2
Part 1 of 2 (a) Construct a 90%90 \% confidence interval for the mean weight. Round the answers to at least three decimal places.
A 90%90 \% confidence interval for the mean weight is 12.818<μ<13.45812.818^{\otimes}<\mu<13.458{ }^{\otimes}.
