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 o=3. The past five days of plant operation have resulted in the following yields 91.6, 88.75, 90.8, 89.66, and 91.5. Find a 95% two-sided confidence interval on the true mean yield. (a) Calculate the sample mean. Round your answer to 2 decimal places. x = i 90.524 (b) Calculate the 95% two-sided confidence interval on the true mean yield. Round your answers to 1 decimal place. 87.9 Sus 93.2
