Note: Round your answers to 3 decimal places. d. Determine the UCL and LCL for an R-chart. Note: Leave no cells blank - be certain to enter " 0 " wherever required. Round your answers to 3 decimal places. e. What comments can you make about the process? The process is out of statistical control. The process is in statistical control. b. Determine X and R. Note: Round your answers to 3 decimal places. c. Determine the UCL and LCL for an X-chart. Note: Round your answers to 3 decimal places. d. Determine the UCL and LCL for an R-chart. Note: Leave no cells blank - be certain to enter " 0 " wherever required. Round your answers to 3 decimal places. Resistors for electronic circuits are manufactured on a high-speed automated machine. The machine is set up to produce a large run of resistors of 1,000 ohms each. Use Exhibit 13.7 . To set up the machine and to create a control chart to be used throughout the run, 15 samples were taken with four resistors in each sample. The complete list of samples and their measured values are as follows: Use three-sigma control limits as in Exhibit 13.7. a. Calculate the mean and range for the above samples. Note: Round "Mean" to 2 decimal places and "Range" to the nearest whole number
