A study of fill volumes is conducted at a food canning factory to determine the level of consistency between the two filling lines, A and B. A random sample of 11 cans taken from line A has a sample average of 8.005 ounces and a sample standard deviation of 0.013 ounces. A similar sample of 16 cans is obtained from line B with a sample average of 7.997 ounces and a sample standard deviation of 0.008 ounces. The quality control manager is interested in finding evidence that there is a difference in the variance in fill volume for the two lines.
