Please help answer this question. Thanks!

(20 points) Suppose y is a random variable whose density is either: f () | H.) = 73 ()+1), Osys1 0, else OSys1 f() | H,)= else Find the Bayes rule and the resulting error probabilities Pr(Do | /1) and Pr(D1 | Ho) for testing Ho versus / with equal priors and uniform costs (C/ = 0, Cy = 1)
