1.49 A cdf Fx is stochastically greater than a cdf Fy if Fx (t) ≤ Fy(t) for all t and Fx (t) <Fy(t) for some t. Prove that if X Fx and Y Fy, then~P(X> t) > P(Y>t)for every tandP(X > t) > P(Y > t) for some t,that is, X tends to be bigger than Y.

Here we have to show X tends to be bigger than Y. From given data we have, Fx(t)≤FY(t) , ∀t Then…

A certain market has both an express checkout line and a super-express checkout line. Let X, denote the number of customers in line at the express checkout at a particular time of day, and let X, denote the number of customers in line at the superexpress checkout at the same time. Suppose the joint pmf of X, and X, is as given in the accompanying table.
