A design engineer wants to construct a mean chart for controlling the diameter for a component used in surgeries. The following table contains measurements (in millimeters) of the diameter for a component. Four samples of five units each were taken at random two-hour intervals. Sample Measurements (in millimeters) 1 9 10 9 7 9 9 3 9 10 10 9 8 8 2 9 8 8 9 4 9 9 9 9 What are the R chart upper and lower control limits? 3.675 and 1.935 3.172 and 2.375 5.872 and 3.828 3,172 and 0.00 4.015 and 0.00
