Suppose the multivariate random variables (Z1, Z2, Z3) have a standard Gaussian distribution on R3. Let the larger eigenvalue of the matrix “ 1221 Z3 V22, be 11 and the smaller one is called 12. (a) [2 mark] Find a formula for 11 and 12 in terms of Z1, Z2, Z3. (b) [1 mark] Define random variables X and Y by X = 11 + 12 Y = 1 -12. Write down the formula for X and Y in terms of Z1, Z2, Z3. (c) (7 marks] Find the density function of [You should explicitly calculate any unknown constants.] (d) (4 marks] Find, for c> 1, the probability P (^> cl2).
