McHuffter Condominiums, Inc., of Pensacola, Florida, recently purchased land near the Gulf of Mexico and is attempting to determine the size of the condominium development it should build. Three sizes of develop-ment are being considered; Small, d1; Medium, d2; and large, d3. At the same time, an uncertain economy makes it difficult to ascertain the demand for the new condominiums. McHuffter's management realizes that a large development followed by a low demand could be very costly to the company. However, if McHuffter makes a conservative small-development decision and then finds a high demand, the firm's profits will be lower than they might have been. With the three levels of demand-low, medium and high. McHuffter's management has prepared the following profit ($000). (20 pts.) payoff table ------------------------------------------- Demand Decision ---------------------------- Alternatives Low Medium High ------------------------------------------- Small, d1 400 400 400 Medium, d2 100 600 600 Large, d3 -300 300 900 -------------------------------------------- a) If nothing is known about the demand probabilities, what are the recommended decision using the Maximax(optimistic), Maximin (pessi- mistic), and Minimax regret approaches? b) If P(low) = 0.20, P(medium) = 0.35, and P(high) = 0.45, What is the recommended decision using the expected value approach? c) What is the expected value of perfect information (EVPI)? You have to use regret table to get EVPI. Suppose that before making a final decision, McHuffter is considering conducting a survey to help evaluate the demand for the new condominium development. The survey report is anticipated to indicate one of two levels of demand: weak(W) or strong(S). The relevant probabilities are as follows: (25 pts) P(W)= 0.3 P(low/W) = 0.50 P(low/S) = 0.10 P(S)= 0.7 P(medium/W)= 0.40 P(medium/S)= 0.25 P(high/W) = 0.10 P(high/S) = 0.65 BDSC 340.001-3 d) Construct a decision tree for this problem and analyze it. e) What is McHuffter’s optimal decision? f) What is the expected value of the survey(sample) information?

Answer the following unrelated short-answer questions.

a. An economist makes the following argument – “The economy basically self-corrects out of recessions. When the economy is in recession, unemployment creates an excess supply of labor, which causes wages to fall. As a result, employers increase their hiring and the economy recovers automatically.” How would a Keynesian respond to this claim?

b. Consider an economy where the reserve ratio is ? = 0.2 and the currency ratio is ? = 0.2. What Fed bond purchase is required in order to raise the money supply by $600 billion?

c. In 2019, government purchases of goods and services at all levels of government were $3.75 trillion (about 17% of GDP). Yet, the federal government alone had expenditures of $4.8 trillion. How can you explain this apparent inconsistency?

Consider the two assets A and B for which returns (%) under different conditions of economy are given as below.

1. Find the expected return of each asset
2. Find the risk (as measured by standard deviation of return) of each asset
3. If an investor decides to invest $8,000 in stock A and $12,000 in stock B, calculate the expected returns of the investor’s portfolio of stocks A and B.
4. Using the information, calculate the portfolio’s standard deviation if the correlation of the returns between stocks A and B returns is -0.25.

Hi, I would like to know which method should we use when doing physics calculations?

Acceleration = Speed / Time

Let's say we are given 5 measurements of speed and time. S1, S2, S3, S4, S5 and T1,T2,T3,T4,T5.

We are given two methods.

1) Find the mean of speed and time, and find their respective standard deviation and standard error. E.g. speed = 0.5 +- 0.2 m/s and 3 +- 0.2 s, substituting into the acceleration formula and doing the respective uncertainties combinations/

or 2) Find the acceleration of each set e.g. (S1, T1), (S2,T2).... After which we find the mean acceleration from the 5 newly calculated results, standard deviation and standard error?

A stock is expected to pay a dividend of $10 in one year. Its future annual dividends are expected to grow by 20% pa. The next dividend of $10 will be in one year, and the year after that the dividend will be $12 (=10*(1+0.2)^1), and a year later $14.4 (=10*(1+0.2)^2) and so on forever.

Its required total return is 50% pa. The total required return and growth rate of dividends are given as effective annual rates.

Calculate the payback period of buying the stock and holding onto it forever, assuming that the dividends are received as at each time, not smoothly over each year. Note that you will have to find the price of the stock first.

Select one:

a. 1 year.

b. 2 years.

c. 3 years.

d. 4 years.

e. 5 years.

A 3.00 mL aliquot of 0.001 M NaSCN is diluted to 25.0 mL with 0.2 M Fe(NO3)3 and 0.1 M HNO3.

1. How many moles of SCN- are present?

2. If all of the SCN- is complexed with Fe3+ to form FeNCS2+, what is the molar concentration of FeNCS2+?

3. For preparing a set of standard solutions of FeNCS2+, the equilibrium molar concentration of FeNCS2+ is assumed to equal the initial molar concentration of the SCN- in the reaction mixture. Why is this assumption valid?

4. The blank solution used to calibrate a spectrophotometer is 10.0 mL of 0.2 M Fe(NO3)3 diluted to 25.0 mL with 0.1 M HNO3. Why is this solution preferred to simply using de-ionized water for the calibration?
