The Brutus Gourmet Company produces delicious organic 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 127 grams.

When the process is in control, the range in the weight of each sample has averaged 8 grams. Sample size, n= (enter whole number)
