Web13 Let X1,X2 be iid uniform (θ,θ+1). For testing H0:θ=0 versus H1:θ>0, we have two competing tests: ϕ1(X1): Reject H0 if X1>.95,ϕ2(X1,X2): Reject H0 if X1+X2>C. (a) Find the value of C so that ϕ2 has the same size as ϕ1. (b) Calculate the power function of each test. Draw a well-labeled graph of each power function.
