If where a and b are constants, express the moment generating function of in terms of the moment generating function of .
A population is made up of disjoint subgroups. Let denote the proportion of the population that is in subgroup . If the average weight of the members of subgroup is , what is the average weight of the members of the population?
Show that is stochastically larger than if and only if
for all increasing functions .
Hint: Show that , then by showing that and then using Theoretical Exercise 7.7. To show that if for all increasing functions , then , define an appropriate increasing function .
N people arrive separately to a professional dinner. Upon arrival, each person looks to see if he or she has any friends among those present. That person then sits either at the table of a friend or at an unoccupied table if none of those present is a friend. Assuming that each of the pairs of people is, independently, a pair of friends with probability p, find the expected number of occupied tables.
Hint: Let equal or , depending on whether theth arrival sits at a previously unoccupied table.
Use Table to determine the distribution of when are independent and identically distributed exponential random variables, each having mean.
