2. (10 points) Let X N N(0, 1) and Y N N(0, 1) be independent. In this exercise, we want to investigate the random variable X / Y. a) Introduce the random variable Z 2: X / Y. Determine the conditional probability density fZIY(Z|Y = y)- b) Determine the joint density fzay(Z, y) and consequently nd fz(z). What type of random variable is Z = X / Y
