Suppose the economy of Protoss consists of three people: Fenix, Zeratul, and Tassadar. The following table shows their consumer spending at the given disposable income levels.

a. Identify each individual’s consumption function, i.e., the mathematical equation that describes the individual’s consumption schedule given income. (3 points)

b. Draw the individuals’ consumption functions. Label the graph fully. (3 points)

c. Identify aggregate consumption function. Show the intermediate steps. (Hint: You need to add individual disposable income and consumption spending.) (2 points)

d. On a separate graph, draw the aggregate consumption function. (1 point)

e. Suppose everyone’s disposable income becomes $6000. Calculate the individual consumption (for each person) and aggregate consumption. (2 points)

Modified problem. Please answer the questions a, b, c.

Question 1

For the dataset: 20, 20, 10, 10, 40, 50, 20, 30, 10, 20, 50, 60, 20, 30, 50, 20, 30, 40, 30, 30, 30, 50, 40 calculate the max, min, mode, median and mean.(20%)

Draw a boxplot with inner and outer fence

For the data in part (i), if the value 60 was replaced by 2000, what would you call this value in the dataset? What could be the explanation for such a value? How can you through the boxplot decide if this value should be excluded from your analysis

Draw a histogram of the data with four equal sized classes and comment how close to a normal distribution the data look like being

What would be the new values for the three measures of central location with the value of 2000 instead of 60. Comment on the differences

Calculate the coefficient of variation for the population from which the data are drawn.

Analyze new monetary policy actions undertaken by the U.S. government from 2000 - 2010 by describing their intended effects, using macroeconomic principles to explain the actions.

•You should specifically state what the intent of the actions were - for instance, the Fed may have used expansionary policy to help expand the economy in response to a recession. Such policies could have been buying up government bonds - this puts money into the economy since the Fed is buying these bonds from a bank and then the bank can use that money in the economy. This open-market operation increases the money supply.

Then, use our macroeconomic principles and models (like the Supply and Demand of Money model, AD-AS model to show the impact of interest rates on equilibrium GDP, Phillips Curve, etc.) to explain why the action would lead to the outcome desired by the government.

please relate the answer to 2000-2010 and please add a reference, thank you so much!

• FIN Ltd is considering the purchase of a new photocopier to replace the existing one. The following information is available.

• The total cost of the NEW is $16,000. The NEW is to be depreciated using the straight-line method with an effective life of 10 years.

• The OLD was purchased 5 years ago for $7500. When it was purchased, the asset had an expected useful life of 15 years and an estimated market value of zero at the end of its life. The machine currently has a market value of $1000.

• As a result of the NEW , sales in each of the next ten years are expected to increase by $2000, and product costs (excluding depreciation) will represent 50% of sales.

• As a result of the NEW, current assets will increase by $5,000 and current liabilities will increase by $2000. The net working capital will be recovered in the terminal year.

• The terminal value of the NEW at the end of Year 10 will be $3000.
• The company is subject to a 30% tax rate and the cost of capital is 15%.

i) Compute the NPV. Should FIN accept the project and why?

1.- Modern Portfolio Theory: A Portfolio of Risky Securities Is Not Necessarily a Risky Portfolio.

Given the portfolio investments and the price changes below, compute the returns on the whole portfolio. Assume that you have the same amount invested in each stock. The initial amount is $2000 on each company for a total investment of $10,000.

            Initial Price      Shares Bought End of Year Price    Value at End of Year     Returns

Co. A                $40                                          $20     

Co. B                $80                                          $0

Co. C                $20                                          $50

Co. D                $60                                          $90

Co. E                 $50                                          $70

a) How many shares of each company are held in the portfolio given that the amount invested in each company is $2000?

b) What is the value of each security and the total portfolio at the end of the year?

c) What is the total portfolio return for the year?

d) Confirm the answer in part c) by calculating the weighted average portfolio return.                           Portfolio Returns = W_A*R_A + W_B*R_B + ….

Consumer Reports provided extensive testing and ratings for more than 100 HDTVs. An overall score, based primarily on picture quality, was developed for each model. In general, a higher overall score indicates better performance. The following (hypothetical) data show the price and overall score for the ten 42-inch plasma televisions (Consumer Report data slightly changed here): Brand Price (X) Score (Y) Dell 3800 50 Hisense 2800 45 Hitachi 2700 35 JVC 3000 40 LG 3500 45 Maxent 2000 28 Panasonic 4000 57 Phillips 3200 48 Proview 2000 22 Samsung 3000 30 Use the above data to develop and estimated regression equation. Compute Coefficient of Determination and correlation coefficient and show their relation. Interpret the explanatory power of the model. Estimate the overall score for a 42-inch plasma television with a price of $3600. Perform test of significance for slope coefficient.

write a java program that implements the splay tree data structure for the dictionary abstract data type.

Initially the program reads data from "in.dat", and establishes an ordinary binary search tree by inserting the data into the tree. The data file contains integers, one per line.

in.dat file contents:

3456
5678
1234
2369
7721
3354
1321
4946
3210
8765

Then the program starts an interactive mode. The commands are as follows.

S 1000 - splay the tree at 1000

F 2000 - search/find the node with key 2000

I 3000 - insert a node with key 3000

D 4000 - delete the node with key 4000

For each command,

1. Report appropriate message after the command is executed. Examples are:

Splay is done

Search is successful

Search is unsuccessful

The key is inserted into the tree

Duplicated keys

The key is deleted from the tree

The key is not in the tree

2. Display the new tree.
