5. Suppose that we are fitting the straight line Y₁ = Bo+B₁xi +, but the variance of the Y's now depend on the level of x; that is, 0² V(Y₁|x₁) = ², V(Y₂|x2) = ²₂, ..., V(Yn|™n) = Wn where the w; are known constants, often called weights. Find the maximum likelihood estimates for 30 and 3₁. Assume that E(₁) = 0 and that Y's are Normally distributed. Show all your work and circle your final answers.
