1. let Yn denote the nth order statistic of a random sample from a
distribution of the continuous type that has cdf F(x) and pdf f(x)=F'(x).
Find the limiting distribution of Zn=n[1-F(Yn)]
2.Let Xn have a gamma distribution with parameter α=n and β, where β is
not a function of n. Let Yn=Xn/n. Find the limiting distribution of Yn.
thanks
