For n > 1, let X„ be a continuous random variable with the probability density function
are called Pareto random variables and are used to study income distributions.
(a) Calculate cn, n > 1.
(b) Find E(X„), n > 1.
(c) Determine the density function of Z, = In X„, n > 1.
(d) For what values of m does E(X,7+1) exist?
