Example - Underweight Bags of Flour - Atlas Corp. sells bags of flour with a nominal mass of 50kg. The company's quality control system ensures that on average 6% of their bags are underweight (note that this refers to the number of underweight bags, not to how much underweight they are on average). - What is the probability that. in a certain shipment of 200 bags, less than 4% are underweight? ' p = 0.06 and n = 200 _ p(1 p) _ 0.06(1 0.06) _ 0p - l n T _ 0.016792856 _ 0.04 0.06 0.016793 - We want to know the probability that less than 4% = 0.04 of the bags are underweight, so we are looking for the area to the left of z = 1 .19 z = -'l.19
