Suppose that X is a continuous rv with pdf f(x) supported on r > 0. Let F(x) be the cdf. Show that E(X) = [" ={(e) dz = (1 - F(2) d . zf(x) dz = Hint: Since z > 0, you can write z = dt. Plug this into the definition of the expected value and swap the order of integration (and look at your Vector Calculus notes to confirm that you can swap the order of integration).

4. Suppose that X is a continuous rv with pdf f(x) supported on r > 0. Let F(x) be the cdf. Show that E(X) = af(e) da = (1 – F(2)) da . 5 dt. Plug this into the definition of the expected value Hint: Since a > 0, you can write = and swap the order of integration (and look at your Vector Calculus notes to confirm that you can swap the order of integration).
