2. (a) Let X be a positive continuous random variable with Vk EN: EX E R.
i. Show that E[X] = S (1- Fx(x))dx. Hint: Write 1 Fx(x) in terms of
an integral of the pdf, then switch the order of integration.
ii. Find an expression for E[X*] (where k E N) of the form (1-Fx(x))h(x)dx
for a function h which you should specify.
