The Crunchy Potato Chip Company sells chips in boxes with a net weight of 24 ounces per box (680 grams). Each box contains ten individual 2.4-ounce packets of chips. Product design specifications call for the packet-filling process average to be set at 69.0 grams so that the average net weight per box will be 69 grams. Specification width is set for the box to weigh 680±10 grams. The standard deviation of the packet-filling process is 8.0 grams per box. The target process capability ratio is 1:33.
