A soft drink can filling machine operator knows the machine is supposed to fill cans to 12 ozs. and the standard deviation for the volume of all cans filled by the machine is 0.19 ozs. In order to determine if the cans are being under or overfilled, samples of 25 cans are drawn from each production run and the mean volume of the sample found. Find the 95% control limits that would be used on a control chart for the can filling process.
