![Please use the accompanying Excel data set or accompanying Text file data set when completing the following exercise.
The yield of a chemical process is being studied. From previous experience, yield is known to be normally distributed and \(\sigma = 3\). The past five days of plant operation have resulted in the following yields 91.6, 88.75, 90.8, 89.60, and 91.1. Find a 95% two-sided confidence interval on the true mean yield.
(a) Calculate the sample mean. Round your answer to 2 decimal places.
