A manufacturer of computer paper has a production process that operates continuously throughout an entire production shift. The paper is expected to have a length of 11 inches and the standard deviation of the length is known to be 0.02 inch. At periodic intervals, samples are selected to determine whether the mean paper length is still equal to 11 inches or whether something has gone wrong in the production process to change the length of the paper produced. If such a situation has occurred, corrective action is needed. Suppose a random sample of 100 sheets is selected, and the mean paper length is found to be 10.998 inches. Set up a 95% confidence interval estimate of the population mean paper length. Continue to elaborate upon how you can use this acumen to improve upon decision-making in business
