1. (Risk minimization and a simplified binary classifier) In lecture, we learnt about the Neyman-Pearson framework: we seek to find a "best" critical region that maximizes the power of the test while main- taining a given significance level. Another major paradigm in the literature to define a “best” critical region is known as risk minimization that we now introduce. Let X ~ N(μ, 1). We are interested in testing Ho p=0, H₁ : µ = 1. As we only have a single sample X, we intend to use the test statistic T and critical region C to be respectively T=X, C= {X> c}, where c> 0 is a constant. Let be the standard normal cdf. (a) Prove that the probability of type I error is a(c) = 1 − (c). The bracket of c on the left hand side is to indicate the dependence on c of a, that is, a is a function of c.
