A machine is set to fill cereal boxes with a mean weight of 500 grams
of cereal per box. The standard deviation is known to be 25 grams. A
random sample of 100 filled boxes is taken and the mean weight of
cereal per box is computed as 504 grams. Is there reason to believe
that machine is over filling the boxes use a = 0.05
