NUMBER 1: Y1, Y2 is a random sample which is taken from N{1,1). X1, X2, X3, X4 is a random sample taken from N{0,1]. The two random samples are independent. From this, answer the following questions: 1.) What is the distribution of X + )7? 2.) Determine the distribution of: X5 +X +(Y1 -1)2 + (Y2 1)2
