A recent census asked respondents to state the highest level of education that they had received. The responses were 39% High school, 45% TAFE or Undergraduate Degree, 13% Higher Degree and 3% Other.
The mayor of a small country town held a similar survey. Below are observed counts for each of the education levels for 250 respondents from the town: Highest Education Level
|
Highest education level |
Observed count |
|
High school |
115 |
|
Tafe or uni |
105 |
|
Higher degree |
20 |
|
Other |
10 |
a) If the counts observed for the town matched that of the census, what would be the expected counts for
each education level?
b) To see if these results are unusual, should you perform a goodness-of-fit test or a test of independence?
c) State your hypotheses.
d) How many degrees of freedom are there?
e) Find x2 and the P-value.
f) State your conclusion (use α = 0.05) in the context of the question.

A U.S. firm has a subsidiary in Great Britain and faces the following scenario:
|
State |
Probability |
Spot Rate |
C* |
C |
Proceeds from Fwd. contract |
Dollar value of hedged position |
|
State 1 |
40% |
$2.50/£ |
£2,000 |

|
State 2 |
60% |
$2.30/£ |
£2,500 |
a. Fill in the dollar value of the cash flow (C) in the table above.
b. Estimate your exposure to exchange rate risk (b).
c. Compute the proceeds from the forward contract if you hedge this exposure. Assume the forward rate is $2.45/£. Fill in the proceeds in the appropriate box in the table above. Use two decimal places in your calculations.
d. Compute the dollar value of the hedged position and fill in the blanks in the table above.
e. Calculate the variance of the un-hedged position.
f. If you hedge, what is the variance of the dollar value of the hedged position?
Note C* refers to GPB Cash flow and C refers to the USD equivalent using the spot rate

1. Explain how different experimental errors can affect the reported value of Keq. Clearly state why the reported value of Keq would be bigger or smaller than the actual value. Examples may include:
a) You thought the spectrometer was set to read trasmittance/absorbance at a wavelength of 447 nm, but it was actually set at 520 nm.
b) You thought you measured the transmittance/absorbance in a cuvetter with a 1-cm pathlength, but it was actually 1.5 cm.
2. Would your Keq results have been affected if you had chosen to use 5.00 mL of KSCN and altered the volume of Fe(NO3)3 solutions used?

Answer A- H please
a) Draw a Supply Curve and the Demand Curve for the Sugar
Label the supply S1 and the demand D1. Label on the vertical axis P for the equilibrium price and label the horizontal axis Q for the equilibrium quantity.
We currently have the sugar market in equilibrium at a price of $3 per pound and 100,000 pounds.
Now assume that the state government just announced a new price floor program for the sale of sugar.
Under this program, a price floor for sugar will be set at
20% above the current market equilibrium price of
sugar.
We also know that the Es of sugar is 1.20 and that the Ed for sugar is 0.80.
Now, given this information, answer the following questions.
b) State the dollar amount of the price floor and label on your graph PF for Price Floor.
c) Using the Definition Formula for Elasticity of Supply or Es (found in the lectures for Chapter 6) determine the number for the new Quantity Supplied after the price floor is imposed. Please show how you got your answer.
d) Label the new Quantity Supplied on your graph as Qs along the horizontal axis.
e) Using the Definition Formula for Elasticity of Demand or Ed (found in the lectures for Chapter 5) determine the number for the new Quantity Demanded after the price floor is imposed. Please show how you got your answer.
f) Label the new Quantity Demanded on your graph as Qd along the horizontal axis.
g) Please determine the market situation we now have after the price floor was imposed. Use numbers in your answer.
h) Explain now what will happen in this market starting from the situation you stated in (g) above.

Pls do not handwritten for easy reading === ===
Question:-
1a) What is Linear Programming(LP)?
1b) Describe a Linear Programming problem in 300 words so that
people who have not had any exposure to Microsoft Excel Solver will
understand what LP is(Note: Please do not write a
textbook-definition-ish description. You have to explain LP in your
own words so that someone like your grand-parents or nephew 12 yr
old who have not heard about anything about operations research
would understand)
