Refer to the table Factors for Computing Control
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 butter at an average speed of 66 mph. To monitor these devices and to maintain the highest quality, Autopitch executive Neil Geismar takes samples of 9 devices at a time. The average range is 4 mph. a) Using this information, construct control limits for the x-chart. UCL)- 67348 mph (round your response to three decimal places). LCL-64.662 mph (round your response to three decimal places) b) Using this information, construct control limits for the R-chart UCLR-mph (round your response to three decimal places)
