f(0) =
ſ1,
=> 0
-1, x < 0.
Which of the following statements for Y = f(X) is true?
[1 Point]
(A) E[Y] = 0.
(B) E[Y) = 1.

7. A particle moves randomly to the left or the right in a step-by-step fashion. Its position after the
nth step (n = N) is modelled by Sn = X1 + ... + Xn where X1, X2, ... are i.i.d. random variables
with X1 ~U({-1,1}). Which of the following statements is false?
[1 Point]
(A) The expected position of the particle after n steps (E[Sn]) is 0.
(B) The expected square of the position of the particle after n steps (E[S2]) is n.
(C) Sin converges to zero in probability as n → 00.
(D) For large n, the position of the particle can be approximately described by a N (0,n)-distribution.
(E) For large k e N, the positions of the particle after n resp. n + k steps (Sn resp. Sn+k) are
independent
