Question
A manufacturing firm employs three analytical plans for the design and devel.
opment of a particular product. For cost reasons, all three are used at varying
times. In fact, plans 1, 2, and 3 are used for 30%, 20%, and 50% of the products
respectively. The defect rate is different for the three procedures as follows:
P(D|P2) = 0.03,
P(D|P3) = 0.02,
%3D
P(D|Pt) = 0.01,
where P(D|P;) is the probability of a defective product, given plan j. If a random
product was observed and found to be defective, which plan was most likely used
and thus responsible?
