Exercise 8.55 Let X1, X2, . . . be independent random variables, each having the Cauchy distribution.

Show that An = n−1(X1 + X2 + · · · + Xn) converges in distribution to the Cauchy distribution as n →∞. Compare this with the conclusion of the weak law of large numbers.

Exercise 8.56 Let Xn, Yn, Z be ‘constant’ random variables with distributions P

Xn = −

1 n

= 1, P

Yn =

1 n

= 1, P(Z = 0) = 1.
