2. Consider two equally probable 1-dimensional densities as below: |x ail P(x[w;) exp (-1). , for i = 1,2, and b > 0 a- Write an analytic expression for each density function. Namely, you have to normalize a; and bi for each function. b- Write the likelihood ratio P(x[W)/P(x|w2) Sketch a graph of a likelihood ratio for the case ay = 1, b1 = 2, a2 = 0, b2 = 1 C
