A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 416 gram setting. It is believed that the machine is overfilling the bags. A 39 bag sample had a mean of 423 grams. Assume the population standard deviation is known to be 25. Is there sufficient evidence at the 0.05 level that the bags are overfilled
