A cereal manufacturer has a machine that fills the boxes. Boxes are labeled "16 ounces," so the company wants to have that much cereal in each box. But no packaging process is perfect, so there will be minor variation. If the weight was set to 16 ounces, then half of the boxes would be underweight, which would not make consumers happy. So, manufacturer sets the weight to 16.3 ounces for filling the boxes. Based on their experience the company knows that the standard deviation will be 0.2 ounces. If the boxes are labled 16 ounces(and expected to weight 16 ounces), then what precentage of the boxes will be underweight? Include a sketch in your answer.
