i Suppose you have a sample of n observations of z. 2 follows a Normal distribution N(0,0%). Someone asks you to calculate: Σε – 3)? (1) i=1 What does this formula measure? ii How would you calculate E[<?=1(21 – 7)?)? iii Suppose you have also n observations on r ~ N(3,0%). x is uncorrelated with z. You sum i to z to obtain y = 1 + 2. What is the mean, variance and distribution of y?
