A chemical ingredient is packed in metal containers. A large shipment of these containers has been delivered to a manufacturing facility. The mean bulk density of this ingredient should not be less than 0.15 g/cm3. Suppose that lots of this quality are to have a 0,95 proba-
bility of acceptance. If the mean bulk density is as low as 0.1450, the proba-
bility of acceptance of the lot should be 0.10. Suppose we know that the stan-
dard deviation of bulk density is approx-
imately 0.005 g/cm2. Obtain a variables sampling plan that could be used to sen-
terice the lots.
