Would greatly appreciate some help! Resistors for electronic circuits are manufactured on a high-speed automated machine.

Aesistors for electronic circuits are manufactured on a high-speed nutometed machine. The machine is set op to produce a tarqie fun of resictors of 1,000 ohms each, Use Exhl lbital3,7. To sef up the machine and to create a control chart to be used throughout the run, 15 samples were taken with four resistors in each sampie. The complete list of samples and their measured vatues are os follows. Use three-sigme control limits. a. Calculate the mean and range for the above samples. (Round "Mean" to 2 decimal places and "Range" to the nearest whole number.) b. Determine X and R. (Round your answers to 3 decimal places.) c. Determine the UCL and LCL for a X chart. (Round your answers to 3 decimal places.) d. Determine the UCL and LCL. for R.chart. (Leave no cells blank - be certain to enter "o" wherever required, Round your answers to 3 decimal places.) e. What comments can you make about the process
