Let X1 and X2 have joint PDF f(x1,x2)=x1+x2 for 0 <x1 <1 and 0<x2 <1.(a) Find the covariance and correlation of X1 and X2. (b) Find the conditional mean and conditional variance of X1 given X2 = x2.
f(x1, x2) = -2(x1)(x2)+ (x1)^3 + (x2)^3 a) Find a maximum in the region where x1 ≤ 1 and x2 ≤ 1 (Hint: remember to check what happens when x1 = 1 and x2 = 1) b) Now consider (x1, x2) ∈ R 2 , that is, the entire two-dimensional space where x1 and x2 are in[−∞,+∞]. Is there a maximum?
