Asset

     (in %)

Fund 1

    3.4086

Fund 2

    2.975

Fund 3

    4.7056

Answer the following questions:

a) Suppose your allocations for the portfolio are given as 1/6 for asset one, 1/3 for asset two, 1/2 for asset three, what is the standard deviation for this portfolio?

b) Suppose that your portfolio has initial value as $300 million, given that your confidence level as 95% and assuming the normal distribution for asset returns, what is the VaR (Value at Risk) for your portfolio? What is the meaning of VaR? Is the normality assumption appropriate for the assessment of VaR?

Scott and Linda have been saving to pay for their daughter Casie's college education. Casie just turned 10 at (t = 0), and she will be entering college 8 years from now (at t = 8). College tuition and expenses at State U. are currently $14,500 a year, but they are expected to increase at a rate of 3.5% a year. Ellen should graduate in 4 years¾if she takes longer or wants to go to graduate school, she will be on her own. Tuition and other costs will be due at the beginning of each school year (at t = 8, 9, 10, and 11). So far, Scott and Linda have accumulated $15,000 in their college savings account (at t = 0). Their long-run financial plan is to add an additional $5,000 in each of the next 4 years (at t = 1, 2, 3, and 4). Then they plan to make 3 equal annual contributions in each of the following years, t = 5, 6, and 7. They expect their investment account to earn 9%. How large must the annual payments at t = 5, 6, and 7 be to cover Casie's anticipated college costs?

a. $2,412.76

b. $2,177.51

c. $1,965.21

d. $2,292.12

e. $2,068.64

What is the age distribution of patients who make office visits to a doctor or nurse?...

What is the age distribution of patients who make office visits to a doctor or nurse? The following table is based on information taken from a medical journal.

Age group, years Under 15 15-24 25-44 45-64 65 and older

Percent of office visitors 20% 15% 25% 20% 20%

Suppose you are a district manager of a health management organization (HMO) that is monitoring the office of a local doctor or nurse in general family practice. This morning the office you are monitoring has eight office visits on the schedule. What is the probability of the following?

(a) At least half the patients are under 15 years old. (Round your answer to three decimal places.)

Explain how this can be modeled as a binomial distribution with 8 trials, where success is visitor age is under 15 years old and the probability of success is 20%?

Let n = 8, p = 0.80 and compute the probabilities using the binomial distribution.

Let n = 8, p = 0.20 and compute the probabilities using the binomial distribution.

Let n = 8, p = 0.35 and compute the probabilities using the binomial distribution.

Let n = 15, p = 0.20 and compute the probabilities using the binomial distribution.

(b) From 2 to 5 patients are 65 years old or older (include 2 and 5). (Round your answer to three decimal places.)

(c) From 2 to 5 patients are 45 years old or older (include 2 and 5). (Hint: Success if 45 or older. Use the table to compute the probability of success on a single trial. Round your answer to three decimal places.)

(d) All the patients are under 25 years of age. (Round your answer to three decimal places.)

(e) All the patients are 15 years old or older. (Round your answer to three decimal places.)
