Canine Gourmet Super Breath dog treats are sold in boxes labeled with a net weight of
15
ounces
(425
grams) per box. Each box contains
10
individual 1.5-ounce packets. To reduce the chances of shorting thecustomer, product design specifications call for the packet-filling process average to be set at
44.0
grams so that the average net weight per box of
10
packets will be
440
grams. Tolerances are set for the box to weigh
440±14
grams. The standard deviation for the packet-filling process is
1.03
grams. The target process capability ratio is
1.67.
One day, the packet-filling process average weight drifts down to
