Suppose a shopkeeper is making bags of 2 pounds of flour with a large quantity of flour bought in
bulk. The shopkeeper keeps adding flour to a bag till the weighing scale reads 2 pounds and seals the
bag. The weighing scale the shopkeeper uses has an error. Hence when the scale reads 2 pounds, the
true weight is distributed normally with a mean of 2 pounds and a standard deviation of 0.08
pounds. What proportion of the bags have less than 1.9 pounds of flour?
Answer correct to 3 decimal places.
