Question:

Let X1, X2 and X3 be three independent and identically distributed random variables having N(0, 1) distribution. If
\(U=\frac{2X^2_1}{(X_2+X_3)^2}\) and \(V=\frac{2(X_2-X_3)^2}{2X^2_1+(X_2+X_3)^2},\)
then which of the following statements is/are true ?

  • U has F1,1 distribution and V has F1,2 distribution
  • U has F1,1 distribution and V has F2,1 distribution
  • U and V are independent
  • \(\frac{1}{2}V(1+U)\) has F2,3 distribution
