Problem 8 (Probability Inequalities) State whether the statements can be labeled with = if equality always holds, and similarly label it with Z or 3 if one of these hold. If no such inequality or equality holds, then label the statement as NONE. Please note that your labeling should be accompanied by a justication. a. Consider a zeromean Gaussian random variable X with unit variance. Compare Q(;I:) with L 22:2 ' b. If X and Y are zero-mean jointly uncorrelated Gaussian random variables with unit variance, compare [[6X+Y] and [[eX][E[eY]. c. We consider a random variable X that has a symmetric p.d.f., i.e., fX(:1:) : f X(:1;) for any x E [R, with [E[|X|] = 1. Compare |P[X 2 1] and g
