iii Suppose you have also n observations on x ~ N(3,0%). r is uncorrelated with z. You sum x to z to obtain y = x + z. What is the mean, variance and distribution of y?
i Suppose you have a sample of n observations of z. follows a Normal distribution N(0,0%). Someone asks you to calculate: Σε- 2 (zi – 2)2 (1) 11 What does this formula measure? ii How would you calculate El (21 - z)?)? iii Suppose you have also n observations on r ~ N(3, 0). v is uncorrelated with z. You sum x to z to obtain y = x + z. What is the mean, variance and distribution of y?
