A continuous RV, x has a cumulative probability distribution function (CDF) defined as follows: Fx(x) = kx for 0xa = [k/(b-a)] x[bx-x/2] for a x b = 1 for x> b where a and bare arbitrary constants. Find the following given that, a = 0.65 and b = 1.75, and k = 0.15. The expected value of the RV Second moment of the RV distribution Standard deviation of the RV distribution Suppose the value of (a = 0.65) represents the median of the RV: x of the CDF indicated.
