Answer all of the following true-false questions. To obtain credit, you must write your answer(either TRUE or FALSE) in the box, and then briefly justify your answer with few sentencesor computations. No points will be awarded for answers without justification. Ifpossible, use math to back up your conclusion. For FALSE statements, you may want toprovide a counterexample or explain how to change the statement to make it true.Note: An answer of TRUE means always true under the given assumptions.(a)Suppose X follows an exponential distribution with parameter λ, thenP(X ≤ 1|X ≤ 2) = e-^.(b)For a random variable X, suppose P(X>0) > P(X < 0).True or False: The expectation of X must be positive.(c)Let ₁ and 2 be two estimators of a parameter 0, where Ô, has a strictlyhigher variance than 2. True or False: If the MSE criterion chooses the estimator ₁,then 2 must be biased.

Given that X follows exponential distribution with parameter . Then the CDF of X is given as:F(x) =…
