26. (24 pts) Suppose that (X1,..., X,) is a random sample from U(0,0), where e > 0. Let X (1), ..., X(n) be the order statistics of the sample. Let U = X(1)/X(n) and V = X(1) + X(n). (a) (4 pts) Find a PDF of (U, X(n)) and show that U and X(n) are in- dependent. You may use Fact 4 in the handout "Minimum sufficient statistics and order statistics". (b) (4 pts) Show that E(U) = 1/n. (c) (4 pts) Show that E(V|X(n)) = (n + 1)X(n)/n. (d) (4 pts) Show that 0 - X(n) and X (1) have the same distribution.
