Unformatted text preview: ) = R ∞ (1F X ( x )) dx . This statement is (a) True. (b) False. Problem 4 Let X be the uniform random variable on the interval [530 , 550]. Then (a) E ( X ) = 530. (b) E ( X ) = 550. (c) E ( X ) = 540. (d) E ( X ) = 350. 1 Problem 5 Let X be an exponential random variable with parameter 5. Then (a) P ( X ≤ 4) = e4 5 . (b) P ( X ≤ 4) = 1e4 5 . (c) P ( X ≤ 4) = 1 5 e4 5 . (d) P ( X ≤ 4) = 1 5 (1e4 5 ). Note that you have to compute P ( X ≤ 4), and not P ( X ≥ 4). 2...
