Chapter 3.3, Problem 12E

An investment firm offers its customers municipal bonds that mature after varying numbers of years.Given that the cumulative distribution function of T,the number of years to maturity for a randomly selected bond, is

F ( t ) = { 0 , t < 1 , 1 4 , 1 ≤ t < 3 , 1 2 , 3 ≤ t < 5 , 3 4 , 5 ≤ t < 7 , 1 , t ≥ 7 ,

find

P(T = 5);
P(T> 3);
P(1.4
P(T = 5 | T = 2).

(d) Suppose that new copies cost $150 and used copies cost $80. Assume the bookstore currently has 50 new copies and 50 used copies. What is the expected value of total revenue from the sale of the next 15 copies purchased? [Hint: Let h(X) = the revenue when X of the 15 purchasers want new copies. Express this as a linear function.] $

The maximum patent life for a new drug is 17 years. Subtracting the length of time required by the FDA for testing and approval of the drug provides the actual patent life of the drug-that is, the length of time that a company has to recover research and development costs and make a profit. Suppose the distribution of the lengths of patent life for new drugs is as shown here. Years, x 3 4 10 11 12 13 p(x) 0.02 0.07 0.07 0.12 0.18 0.20 0.15 0.10 0.05 0.03 0.01 (a) Find the expected number of years of patent life for a new drug. (b) Find the standard deviation of x. (Round your answer to four decimal places.) (c) Find the probability that x falls into the interval u + 20.

A decision maker has a utility function for monetary gains x given by U(x) = (x + 10,000)1/2. (a) Show that the person is indifferent between the status quo and L: With probability 1/3, he or she gains $80,000 With probability 2/3, he or she loses $10,000 (b) Suppose that this person has a painting. If there is a 10% chance that the painting valued at $10,000 will be stolen during the next year, what is the maximum amount (per year) that he/she would be willing to pay for insurance covering the loss of the painting? • What is certainty equivalent? • What is risk premium? (c) Is this person risk-averse, risk-neutral, or risk-taker? Why?
