Q.40 Consider the following two probability density functions (pdfs) ifosxS1 and f)=l0 if0x< 1 otherwise otherwise Let X be a random variable having pdf fEP = Uof. Consider testing H,:fCx)= fo (), Vx E [0,1] against H,:f) = f),Vx E [0, 1] at a = 0.05 level of significance. For which of the following observed values of random observation X, the most powerful test would reject Ho? (A) 0.19 (B) 0.22 (C) 0.25 (D) 0.28
