Suppose a machine for filling cans with lubricatingoil is set so that it will generate fillings which forma normal population with mean 1 gal and standarddeviation 0.02 gal. Set up a control chart of thetype shown in Fig. 537 for controlling the mean, thatis, find LCL and UCL, assuming that the sample sizeis 4.
