(25%) Consider two continuous random variables X and Y with joint pdf:
(a) (5%) Find the constant c
其他申論題
(a) (7%) Find the best linear estimate (i.e. aX +b with a, b being constants to be de termined) of Y given X such that the mean square estimation error is minimized. What is the minimum mean square error thus found?

(b) (7%) Find the best estinate (that is not necessarily linear) of Y given X such that the mean square estimation error is minimized. What is the minimum mean square error thus found?
#462923

7.(8%) The random variable x is uniform in the interval [-5, 5]. Define y = Find C.D.F. Fy(y) and p.d.f. fy(y).
#462931
(10%) Suppose that X is a continuous random variable with cumulative distribution function (CDF) Fx(x) and probability density function (pdt) fx(x), respectively. Let Y = |2X|. Find the CDF of Y.
