13. (8 pts) An endocrinologist studying genetic and environmental effects on insulin production of pancreatic tissue, raised five litters of experimental mice. At age 2 months he sacrificed the mice, dissected out the pancreatic tissue and treated the tissue specimens with a glucose solution. The amount of insulin released from these specimens was recorded in pg/ml. Are there significant differences in insulin release among litters? 1 9 7 5 5 7 2 4 6 7 3 5 3 3 5 9 10 6 Litter 4 15 10 14 8 10 5 8 0231 11

Assume the arithmetic mean returns in these series are normally distributed. Calculate the range of returns that an investor would have expected to achieve 95…
Suppose that there are 4 deaths due to stomach can- cer among workers in a tire plant from 1/1/64 to 12/31/83, while 2.5 are expected based on U.S. mortality rates. Provide a 95% CI for the expected number of deaths from stomach cancer over 20 years among the tire workers. Is the number of cases of stomach cancer excessive?

6. The amount of a loss X follows the uniform distribution on [0, 100]. An insurance policy on this loss has an ordinary deductible of 10, a maximum amount paid of 50, and a coinsurance of 80%, which is applied after the deductible. After losses are subject to inflation of 10%, calculate the expected claim amount paid per loss on this policy.

3(ii) A bank sets up a Special Purpose Vehicle (SPV) for a CDO issue. The SPV wants to understand the risks that they may face, so they run simulations of the annual cash flows out of their portfolio. Selected results of the simulation are shown in the table below. Annual Portfolio Cash Flows Mean Std. Dev. Min. 5th 10th Percentiles 15th 85th 90th (1,172) 16,651 (7,760) (6,800) (4,880) (3,920) 2,480 95th Max. 14,320 15,280 26,400 The SPV wants to hold risk capital to cover its losses to the 95th percentile, and expected CDO payouts for the next five years add up to $100m. How much capital would you advise them to hold, and why?
