Xn are iid Exponential(.5). After using the central limit theorem, Xn is Normally distributed. Use chebychev's inequality to find out how large n be so that P(|Xn-2| < .01) > .95. I tried working...
View Articleconvergence in probability and strong convergence in the discrete case
Show that if you have convergence in probability, then you also have strong convergence in the discrete case. I know that the discrete case means that the sum as i = 0 to n, P(Xi=xi) = 1. I don't know...
