A component of an aerospace product that is manufactured has a critical measurable quality characteristic that must be statistically controlled by means of a control chart. A sampling process was carried out to obtain the following data in inches. a) Construct the X and R control charts for this process. Is the process under statistical control? If necessary revise the test control limits. b) Estimate the mean and standard deviation of the process. c) Perform a complete process capability analysis, if the product specifications are 10 ± 7. Interpret your results.

Question
A component of an aerospace product that is manufactured has a critical measurable quality characteristic that must be statistically controlled by means of a control chart. A sampling process was carried out
to obtain the following data in inches.
a) Construct the X and R control charts for this process.
Is the process under statistical control? If necessary revise the test control limits.
b) Estimate the mean and standard deviation of the process.
c) Perform a complete process capability analysis, if the product specifications are 10 ± 7. Interpret your results.
d) What is the value of the non-conforming fraction of the process and how many defective units per million (PPM) does it equal?
