4. Suppose X is a single observation from one of two possible discrete discributions givien below: x = 0 x = 1 x = 2 x = 3 x = 4 distribution 0: P (X = x) 0.1 0.3 0.2 0.3 0.1 distribution 1: P (X = x) 0.2 02 0.2 0.2 0.2 If the test rejects H0 if and only of X is even. Find the size and power of this test
