Question: Refer to the table Factors for Computing Control Chart Limits (3 sigma) for this problem. Autopitch devices are made for both major- and minor-league teams

Refer to the table Factors for Computing Control Chart Limits (3 sigma) for this problem. Autopitch devices are made for both major- and minor-league teams to help them improve their batting averages. When set at the standard position, Autopitch can throw hardballs toward a better at an average speed of 67 mph. To monitor these devices and to maintain the highest quality, Autopitch executive Noil Geismar takes samples of 8 devices at a time. The average range is 3 mph. a) Using this information, construct control limits for the x-chart. UCL - mph (round your response to three decimal places) LCL - mph (round your response to three decimal places). b) Using this information, construct control limits for the R-chart UCLA - mph (round your response to three decimal places). LCLR-mph (round your response to three decimal places). ed Data Table res resp Sample Size, n ct c res 2 3 4 5 6 7 Mean Factor, A 1.880 1.023 0.729 0.577 0.483 0.419 0.373 0.337 0.308 0.266 Upper Range, D4 3.268 2.574 2.282 2.115 2.004 1.924 1.864 1.816 1.777 1.716 Lower Range, D3 0 0 0 0 0 0.076 0.136 0.184 0.223 0.284 res 9 10 12 Print Done
