Suppose you have n suitcases and suitcase i holds Xi dollars where X1, X2, …, Xn are iid continuous uniform (0, m) random variables. (Think of a number like one million for the symbol m.) Unfortunately, you don’t know Xi until you open suitcase i.
Suppose you can open the suitcases one by one, starting with suitcase n and going down to suitcase 1. After opening suitcase i, you can either accept or reject Xi dollars. If you accept suitcase i, the game ends. If you reject, then you get to choose only from the still unopened suitcases.
"Can I assume that Tau_i is m if i ==n, is 1/2 m at i ==1, and 0 at i ==0?"

Suppose Y = X1 + X2, where Xi ? exp(1) for i = 1, 2. Determine the distribution of Y
Suppose n numbers X1, X2, . . . , Xn are chosen from a uniform distribution on [0, 10]. We say that there is an increase at i if Xi < Xi+1. Let I be the number of increases. Find E[I].
Suppose X1, X2, . . . are independent discrete random variables, having the same distribution, and E[Xi] > 0, for each i. Is thus true for any two positive integers n and m?: Why not, or why yes?
Problem 4 Suppose X1, ..., Xn ~ f(x) independently. Let u = E(Xi) and o2 = Var(Xi). Let X Xi/n. (1) Calculate E(X) and Var(X) (2) Explain that X -> u as n -> co. What is the shape of the density of X? (3) Let XiBernoulli(p), calculate u and a2 in terms of p. (4) Continue from (3), explain that X is the frequency of heads. Calculate E(X) and Var(X). Explain that X -> p. What is the shape...
11. Let X1, X2, X3 and X4 be independent lifetimes of memory chips. Suppose that Xi N(300, 102) for i = 1, 2, 3, 4 where the parameters are measured in hours. Compute the prob- ability that at least two of the four chips lasts at least 310 hours. (You may leave your answer in terms of an integral, in terms of, or you may leave your answer as an actual real number).
Suppose that Xi, X2,..., Xn are independent random variables (not iid) with densities x, (x^, where 6, > 0, for i-1, 2, , n. versus H1: not Ho (c) Suppose Ho is true so that the common distribution of X1, X2,..., Xn, now viewed as being conditional on 6, is described by where θ > 0. Identify a conjugate prior for 0. Specify any hyperparameters in your prior (pick values for fun if you want). Show how to carry out...
