Part C

1) 97. 1) A product is made up of two subsystems in series. The first subsystem consists of 20 components in series. The second subsystem consists of 3 components in parallel. The components in subsystem 1 are all of the same design and each has a 1/10,000 chance of failure. The parallel components each has a 3/10,000 chance for failure. What is the overall reliability of the system?

2) A quality control engineer monitors the quality of a cylinder production line. He regularly selects a sample of 5 units and measures the diameters. The specification requires the diameter to be 6 inches plus/minus 0.1 inch. The following is a record of the measurements.Is the production process in control? Please use X bar and R charts to make an assessment.
