Let Y.Y2, ,Yn be independent standard normal random variables. That is, Y i-1,... ,n, are iid N(0, 1) random variables. 25 a) Find the distribution of Σ 1 Y2 b) Let Wn Y?. Does Wn converge in probability to some constant? If so, what is the value of the constant?
Section 2 2.1 In Example 2.2.1, if X 3 with probability 1/2 each, show that Xo with probability 1/2 and X--oo with probability 1/2 Hint: Evaluate the smallest value that (Xi ++X) /n can take on when Xn 3-1. Example 2.2.1 Estimation of a common mean. Suppose that Xi,, X, are independent with common mean E(X) ξ and with variances Var(X)-ơi, (Different variances can arise, for example, when each of several observers takes a number of observations of , and...
(c) Let N~DU(100), and let X have the value 10, 20, 25, or 50 with probability 1/4 each, independent of N. If N > X, repeatedly subtract X from N until the result is X or smaller. Let Y be the number left over after this repeated subtraction. The number Y is almost the same as the remainder left over after dividing N into X equal parts, ercept that Y will equal X, not 0, if N is evenly divisible...
Please do exercise 129:
Exercise 128: Define r:N + N by r(n) = next(next(n)). Let f:N → N be the unique function that satisfies f(0) = 2 and f(next(n)) =r(f(n)) for all n E N. 102 1. Prove that f(3) = 8. 2. Prove that 2 <f(n) for all n E N. Exercise 129: Define r and f as in Exercise 128. Assume that x + y. Define r' = {(x,y),(y,x)}. Let g:N + {x,y} be the unique function that...
