A certain dry cereal is packaged in 22​-oz boxes. The machine that fills the boxes is set so​ that, on the​ average, a box contains 22.5 oz. The​ machine-filled boxes have contents weights that can be closely approximated by a normal curve. What is the probability that a randomly selected box will be underweight​ (that is, below the stated weight of 22​-oz) if the standard deviation is 0.5 ​oz? If the standard deviation is 0.5 ​oz., the probability of a box being underweight is ______% (ROUND to the NEAREST TENTH)
