[12 pts] Suppose we observe a random variable X having the Exponential(1/1) distribution with density fx (x; )) = if x 2 0 0 otherwise, We want to test Ho : A = An against H1 : A = M1. If X1 > >0, find the critical region of the likelihood ratio test at level of significance o. Note: you need to work out the boundary value of the critical region in terms of the provided quantities (notations)
