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 8 inche 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 8 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 8.002 inches. A 95% confidence interval estimate for the population mean paper length is 7.99612 su s 8.00788. Is it true that you do not know for sure whether the population mean is between 7.99612 and 8.00788 inches? Explain. Choose the correct answer below. O A. It is false because the sample mean fals within the interval. O B. It is false because the sample mean falls outside the interval. O C. Itis true beçause the population mean will be in the interval only 95% of the time. O D. It is true because the population mean will be in the interval only 5% of the time.
