Develop an x chart and an r chart and plot the values


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, 15 samples were taken with four resistors in each sample. The complete list of samples and their measured values are as follows:

Develop an _X chart and an R chart and plot the values. From the charts, what comments can you make about the process?
