The label on a bottle of liquid detergent shows contents to be
12 ounces per bottle. The production operation films the bottle
unifornly according to the following probability density function.
f(x) = 8 for 11.975 ≦ x ≦ 12.100
0 elsewhere
Quality control accepts a bottle that is filled to within 0.2
ounces of the number of ounces shown on the container label. What
the probability that a bottle of this liquid detergent will fail
to meet the quality contral standard?
