Problem 5: A total of 6 measurements are made of the mass of aninjected molded part. The measurements are: [2.68 kg 2.66 kg 2.16kg 2.12 kg 2.50 kg 2.96 kg] a) Determine the average mass based onthe measurements. (5 points) b) Determine the uncertainty in themass at a 95% confidence interval based on the measurements. (10points) c) Determine the uncertainty in the estimated mean at a 95%confidence interval based on the measurements. (5 points) d)Determine the 95% confidence interval for the true standarddeviation value based on the measurements. (10 points)
