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 10.13. 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.

Problem 10-25 (Algo)
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 10.13.
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.
