# Question

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 0.15g/cm3. Suppose that lots of this quality are to have a 0.95 probability of acceptance. If the mean bulk density is as low as 0.1450, the probability of acceptance of the lot should be 0.10. Suppose we know that the standard deviation of bulk density is approximately 0.005/cm3. Obtain a variables sampling plan that could be used to sentence the lots.
