2. A quality-control supervisor in a cannery knows a cannery knows that the exact amount in each can will vary ll. because there are certain uncontrollable factors that aff ect the amount of f The mean fill per can is important, but equally important cans will contain too little and others too much. s the variation of fill. If the variance of the fl IS Suppos determine e regulatory agencies specify that the variance of the amount of fill should be l whether the process is meeting this specification, the supe rvisor randomly selects 10 cans and weights the contents of each.
