The Canine Gourmet Company produces delicious dog treats for canines with discriminating tastes. Management wants the$$ box$-$filling line to be set so that the process average weight per packet is grams. To make sure that the process is in$$ control, an inspector at the end of the filling line periodically selects a random box of packets and weighs each packet. When the process is in$$ control, the range in the weight of each sample has averaged grams.
