Can someone please help me with this? Thank you!!
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. To set up the machine and to create a control chart to be used throughout the run, 10 samples were taken with two resistors in each sample. The complete list of samples and their measured values are as follows:
Develop an X-bar chart and an R chart. Use three-sigma control limits for both charts.
