4.Problem abstract

For a given unit of an aircraft, it shows a kind of feature (high quality, reliability and sensitivity), and we want to classify it (made in which company).

Assume n number of autopilots are installed in n aircraft, respectively, and experienced flight commission. Half of autopilots are made in A company, another half made in B company. Because of different manufacturing process and quality management, they have different probability densities. It can be abstracted as: Single Measurement, c=2, Different Densities, Equal A Priori Probabilities. Furthermore, we can get:
