Consider a two-hypothesis decision problem where (a) Find the likelihood ratio Î(Z). (b) Letting the threshold n

Question:

Consider a two-hypothesis decision problem where
(зi-) and fz(z|H2) exp = ; exp(-|z|) fz(z|Hj) = 2л

(a) Find the likelihood ratio Î›(Z).

(b) Letting the threshold n be arbitrary, find the decision regions R₁ and R₂ illustrated in Figure 11.1. Note that both R₁ and R₂ cannot be connected regions for this problem; that is, one of them will involve a multiplicity of line segments.
