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, 89.57, and 91.0. 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 (b) Calculate the 95% two-sided confidence interval on the true mean yield. Round your answers to 1 decimal place. <μ< i

Sir Please answer it in detail Thanks
Provide an example of how processing, of a specific material of your choosing, can influence the structure of the material which in turn can impact properties. Give an example of how that property could impact performance of that material in an application. Be specific with your example by including the material type, the processing involved, the structural changes, and specific properties that are being influenced. Be clear in how one thing impacts the other. You MUST use relevant equations, graphs, or sketches to support your example (do not use only words).
