Let N be the number of customers that visits a certain shop in a given day. Suppose that
E[N] = e, and Var(N) = v. Let X; be the amount that the ith customer spends on average.
Assume that X;'s are independent of each other and independent of N. Further assume that
that they have same mean and variance i.e., E[X;] = k, Var(X;)
total sales i.e., Y = E; X;. Find E[Y] and Var(Y).
= m. Let Y be the stores
