A family of pdfs that has been used to approximate the distribution of income, city population size, and size of firms is the Pareto family. The family has two parameters, k and 0, both > 0, and the pdf is as follows. k. ek f(x; k, 8) = {k + 1 x 20 x< 6 (a) Sketch the graph of f(x; k, 0). f(x) f(x) k f(x) f(x) k (b) Verify that the total area under the graph equals 1. °k. ek dx = xk + 1 =0 - ek (c) If the rv X has pdf f(x; k, 0), for any fixed b > 0, obtain an expression for P(X s b). (d) For 0 <a <b, obtain an expression for the probability P(a sX s b).
