A paper manufacturer has a production process that operates continuously throughout an entire production shift. The paper is expected to have a mean length of 11 inches, and the standard deviation of the length is 0.03 inch. At periodic intervals, a sample is 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. A random sample of 100 sheets is selected, and the mean paper length is 10.998 inches. A 95% confidence interval estimate for the population mean paper length is 10.99212less than or equalsmuless than or equals11.00388. Is it true that you do not know for sure whether the population mean is between 10.99212 and 11.00388 inches? Explain.
