1. Use the ILT life table to compute p40:50 and p40:50 assuming (40) and (50) are independent lives. Recall that the former corresponds to the joint life status, while the latter refers to the last survivor life status. 2. Find a formula for the survival function of x1:n in terms of the survival function of (x). 3. If the UDD assumption is valid for (x), does UDD hold for x1:n ? 4. Find a formula for the survival function of x:n1 5. If the UDD assumption is valid for (x), does UDD hold for x:n1 ? 6. If the UDD assumption is valid for (x), does UDD hold for x:n ? 7. If the UDD assumption is valid for each of (x) and (y) and if (x) and (y) are independent lives, does UDD hold for x:y ? 1.
