Homework Answers
The control limits for the C chart is defined as:
UCL = cbar + z• sqrt (cbar)
LCL = cbar - z• sqrt (cbar)
Where z is a multiplier (usually it is 3)
Hence the correct option is:
Cbar +/- Three times the square root of cbar

Control charts are to be kept on the thickness measurements for a process that rolls 10-gage copper sheets. The current specification in the sheets is 0.1360+0.0020 inch. After collecting 25 samples of n 5 measurements at approximately half-hour intervals, the data were used to determine Σ L:3.421 inches and R.-0.044 inches, with i1 to 25. Assume that the quality...

Please TYPE your answers to the questions. Thank you! A process quality characteristic that is being monitored is thought to be Normally distributed with a true mean of 90 and a standard deviation of 10. The manufacturer devises a control chart with lower and upper control limits of LCL = 70; UCL = 110, respectively. If the measurement of a manufactured product lies outside these control limits, then the entire process is said to be \out-of-control" and shut down for...
