A) The resistivity of blood is related to its hematocrit, the volume fraction of red blood cells in the blood. A commonly used equation relating the hematocrit h to the blood resistivity ρ (in Ω⋅m) is ρ=1.32/(1−h)−0.79. In one experiment, blood filled a graduated cylinder with an inner diameter of 0.90 cm. The resistance of the blood between the 1.0 cm and 2.0 cm marks of the cylinder was measured to be 246 Ω. What was the hematocrit for this blood?

B) When the starter motor on a car is engaged, there is a 310 AA current in the wires between the battery and the motor. Suppose the wires are made of copper and have a total length of 1.2 mm . What minimum diameter can the wires have if the voltage drop along the wires is to be less than 0.60 VV ? Express your answer in millimeters.

C) Variations in the resistivity of blood can give valuable clues to changes in the blood's viscosity and other properties. The resistivity is measured by applying a small potential difference and measuring the current. Suppose a medical device attaches electrodes into a 1.5-mmmm-diameter vein at two points 5.0 cmcm apart. What is the blood resistivity if a 8.8 VV potential difference causes a 220 μAμA current through the blood in the vein? Express your answer in ohm meters.

Hasbro is considering a new high-profile marketing project to aggressively market a card game version of Monopoly called Monopoly Deal. The Marketing department would spend an extra $1.0 million per year for the next five years to increase TV commercials and print ads featuring Monopoly Deal. The primary Monopoly factory would be expanded at a cost of $5.5 million to manufacture more of the games. Assume that the factory expansion would be completed in the first year of the project. The Marketing department estimates that the marketing campaign will increase Hasbro sales enough to bring in additional cash inflows of $2.5 million per year for the five-year period. Hasbro uses a discount rate of 15% to evaluate projects such as this one. Use a 5-year time horizon, and assume no salvage value of the factory expansion at the end of this period.

1. What is the net present value (NPV) of the project?

2. Based on this NPV, should Hasbro undertake this project?

3. What is the internal rate of return (IRR) of this project? You can find IRR by varying the discount rate in your table until NPV is zero. That new discount rate will be the IRR. Your grade will be based on the completeness of your cash flow table and calculations as well as your answers above.

c-3. What would the cost of equity be if the debt–equity ratio were zero? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)

8. The Capital Asset Pricing Model and the security market line

Wilson holds a portfolio that invests equally in three stocks (wAwA = wBwB = wCwC = 1/3). Each stock is described in the following table:

An analyst has used market- and firm-specific information to generate expected return estimates for each stock. The analyst’s expected return estimates may or may not equal the stocks’ required returns. You’ve also determined that the risk-free rate [rRFrRF] is 4%, and the market risk premium [RPMRPM] is 5%.

Given this information, use the following graph of the security market line (SML) to plot each stock’s beta and expected return on the graph. (Note: Click on the points on the graph to see their coordinates.)

A stock is in equilibrium if its expected return_______ its required return. In general, assume that markets and stocks are in equilibrium (or fairly valued), but sometimes investors have different opinions about a stock’s prospects and may think that a stock is out of equilibrium (either undervalued or overvalued). Based on the analyst’s expected return estimates, Stock A is______ Stock B is ________and Stock C is in equilibrium and fairly valued.

Brokerage Satisfaction with Trade Price Satisfaction with Speed of Execution Overall Satisfaction with Electronic Trades

a. Develop an estimated regression equation using trade price and speed of execution to predict overall satisfaction with the broker. What is the coefficient of determination?

b. Develop an estimated regression equation using trade price and speed of execution to predict overall satisfaction with the broker. What is the SSR?

c. Develop an estimated regression equation using trade price and speed of execution to predict overall satisfaction with the broker. Can you conclude that there is a relationship between satisfaction with speed of execution and overall satisfaction with the electronic trade (can you reject the hypothesis that the parameter is = 0)?

The two roots of a quadratic equation ax^2 + bx + c = 0 can be obtained using the following formula:

r1 = (-b + sqrt(b^2 - 4ac)) / (2a)
and
r2 = (-b - sqrt(b^2 - 4ac)) / (2a)

b^2 - 4ac is called the discriminant of the quadratic equation. If it is positive, the equation has two real roots. If it is zero, the equation has one root. If it is negative, the equation has no real roots.

Write a program that prompts the user to enter values for a, b, and c and displays the result based on the discriminant.
If the discriminant is positive, display two roots.
If the discriminant is 0, display one root.
Otherwise, display “The equation has no real roots”.

Note that you can use Math.pow(x, 0.5) to compute sqrt(x).

Sample Run 1

Enter a, b, c: 1.0 3 1
The equation has two roots -0.381966 and -2.61803

Sample Run 2

Enter a, b, c: 1 2.0 1
The equation has one root -1

Sample Run 3

Enter a, b, c: 1 2 3
The equation has no real roots

Is there a relation between police protection and fire protection? A random sample of large population areas gave the following information about the number of local police and the number of local fire-fighters (units in thousands). (Reference: Statistical Abstract of the United States.)

Use a 5% level of significance to test the claim that there is a monotone relationship (either way) between the ranks of number of police and number of firefighters.

(a) Rank-order police using 1 as the largest data value. Also rank-order firefighters using 1 as the largest data value. Then construct a table of ranks to be used for a Spearman rank correlation test.

(c) Compute the sample test statistic. (Use 3 decimal places.)
