To assure good quality balls that are neither too heavy nor too light, Dennis requires that the rubber core that forms the center of the ball weighs between 57 grams and 62 grams. The molding process that produces the cores has a mean of 61 grams and a standard deviation of 1.5 grams. Dennis follows the industry standard of using 3 limits (z = 3) for statistical process control.
