A new machine has just been installed to cut and roughshape

A new machine has just been installed to cut and rough-shape large slugs. The slugs are then transferred to a precision grinder. One of the critical measurements is the outside diameter. The quality control inspector randomly selected five slugs each half-hour, measured the outside diameter, and recorded the results. The measurements (in millimeters) for the period 8:00 a.m. to 10:30 a.m. follow. Outside Diameter (millimeters) Time 1 2 3 4 5 8:00 87.3 87.5 88.0 87.1 87.0 8:30 86.9 88.5 87.6 87.5 87.4 9:00 87.8 88.5 86.9 87.4 88.1 9:30 86.0 88.0 87.2 87.6 87.1 10:00 86.8 86.8 86.8 87.2 87.3 10:30 88.0 86.2 87.3 87.2 87.9 Picture Click here for the Excel Data File a. Determine the control limits for the mean and the range. (Leave no cells blank - be certain to enter \"0\" wherever required. Round your answers to 2 decimal places.) Picture = LCL = UCL = Picture = LCL = UCL = c-1. Are any means out of control? c-2. Are any ranges out of control?
