It was decided to set up a process to control the output of a machine that was manufacturing buttons. The following measurements of the diameter of the button were made. Each hour a sample of four buttons was taken. The measurement shown in the table is the measured ten-thousandths of an inch in excess of 1.000 inches. The engineering tolerance on this part is 1.000 .005. The following table of data values was collected: What is the value of X bar for day number 7?
2.
Attribute inspection is performed on a lot of motor shafts. The lot of parts is rejected. The parts are supposed to have a diameter of 2 inches and have an engineering tolerance of .015. What is the average dimension of the parts?
3.
A company uses sampling inspection to inspect parts that are sent to their customers. If a lot of parts is rejected from sampling inspection, it is inspected 100% and the rejected parts are sent back to the manufacturing department for rework or scrap. What happens to the overall outgoing quality level as the number of defective parts increases?

ISO standards are reviewed and reissued every:
