uestionQ2. Borneo Steel Corporation produces iron rings that are supplied to ARAAB Co. Ltd.These rings are supposed to have a diameter of 60 cm. The machine that makes theserings does not produce each ring with diameter of exactly 60 cm. The diameter of each ofthe rings varies slightly. It is known that when the machine is working properly, the ringsmade on this machine have a mean diameter of 60 cm. The quality control departmenttakes a random sample of 35 such rings every week, calculates the mean of the diametersfor these rings and makes a 99% confidence interval for the population mean. If eitherthe lower limit of this confidence interval is less than 59.938 cm or the upper limit of thisconfidence interval is greater than 60.063 cm, the machine is stopped and adjusted. Arecent sample of 35 rings produced a mean diameter of 60.038 cm with a standarddeviation of 0.15 cm. Based on this sample can you conclude that the machine needs anadjustment?
