Question: Lockheed Martin is a supplier for the aerospace industry. Recently, the company was considering switching to Cirus Systems, Inc., a new supplier for one of the component parts it needs for an assembly. At issue is the variability of the components supplied by Cirus Systems, Inc., compared to that of the existing supplier. The existing supplier makes the desired part with a mean diameter of 3.75 inches and a standard deviation of 0.078 inches. Unfortunately, Lockheed Martin does not have any of the exact same parts from the new supplier. Instead, the new supplier has sent a sample of 20 parts of a different size that it claims are representative of the type of work it can do. These sample data are shown here and in the data file called Cirus.
