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 batter at an average speed of 61mph. To monitor these devices and to maintain the highest quality, Autopitch executive Neil Geismar takes samples of 12 devices at a time. The average range is 2mph. a) Using this information, construct control limits for the x-chart. UCLx=mph(roundyourresponsetothreedecimalplaces). Data Table
