The Quality Assurance Department for Cola Inc. maintains records regarding the amount of cola in its Jumbo bottle. The actual amount of cola in each bottle is critical, but varies a small amount from one bottle to the next. Cola Inc. does not wish to underfill the bottles, because it will have a problem with truth in labeling. On the other hand, it cannot overfill each bottle, because it would be giving cola away, hence reducing its profits. Its records indicate that the amount of cola follows the normal probability distribution. The mean amount per bottle is 31.2 ounces and the population standard deviation is 0.4 ounces. At 8 A. M. today the quality technician randomly selected 16 bottles from the filling line. Suppose the quality technician selected a sample of 16 Jumbo bottles that averaged 31.08 ounces. What can you conclude about the filling process?

On the other hand, it cannot overfill each bottle. Its records indicate that the amount of cola follows the normal probability distribution when the production is stable. The mean amount per bottle is 31.2 ounces and the population standard deviation is 0.4 ounces.At 8 A.M. today the quality technician randomly selected 16 bottles from the filling line. The mean amount of cola contained in the bottles is 31.38 ounces.Is this an unlikely result of the normal stable process? Is it likely the process is putting too much soda in the bottles? Is the process asking for intervention/ actions of technicians?

it is true
