Oh my goodness! Thank you so much for "you have not used known elementary results about combining variances in linear combinations."! I looked that up and got the answer.. So it's nothing but \frac{7}{16}+\frac{13}{9}+\frac{20}{25} I don't have the exact answer to this but I tried a...

Homework Statement Suppose that: E(X1) = μ, Var(X1) = 7, E(X2) = μ, Var(X2) = 13, E(X3) = μ, and Var(X3) = 20, and consider the point estimates: μˆ1 = X1/3 + X2/3 + X3/3 μˆ2 = X1/4 + X2/3 + X3/5 μˆ3 = X1/6 + X2/3 + X3/4 + 2 (a) Calculate the bias of each point estimate. Is...
