Question 14 - Assignment 4 - Cox + C ezto.mheducation.com/ext/map/index.html?_con=con&external_browser= Assignment 4 14 20 points eBook Problem 13-9 (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 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.
