8.16 LAB: Mileage tracker for a runner

Given the MileageTrackerNode class, complete main() to insert nodes into a linked list (using the InsertAfter() function). The first user-input value is the number of nodes in the linked list. Use the PrintNodeData() function to print the entire linked list. DO NOT print the dummy head node.

Ex. If the input is:

3
2.2
7/2/18
3.2
7/7/18
4.5
7/16/18

the output is:

2.2, 7/2/18
3.2, 7/7/18
4.5, 7/16/18

On the same day the weather is changing moment by moment. It is either sunny (S), cloudy (C) or rainy (R). If currently, it is sunny then it will be S, C or R the next moment with probabilities 0.5, 04, 0.1 respectively. If it is cloudy right now then it will be S, C or R next moment with probabilities 0.3, 0.4, 0.3. If it is rainy at the moment, then it will be S, C or R in the next moment with probabilities 0.2, 0.3, 0.5 respectively. Suppose that the weather is currently sunny. What is the probability that it is not rainy in any of the following three moments?

The expected return on Big Time Toys is 9% and its standard deviation is 21.9%. The expected return on Chemical Industries is 10% and its standard deviation is 29%.

             

a. Suppose the correlation coefficient for the two stocks' returns is 0.2. What are the expected return and standard deviation of a portfolio with 34% invested in Big Time Toys and the rest in Chemical Industries? (Round your answers to 2 decimal places.)
Portfolio's expected return      %
Portfolio's standard deviation      %


b. If the correlation coefficient is 0.7, recalculate the portfolio expected return and standard deviation, assuming the portfolio weights are unchanged. (Round your answers to 2 decimal places.)
Portfolio's expected return     %
Portfolio's standard deviation     %


c. Why is there a slight difference between the results, when the correlation coefficient was 0.2 and when it was 0.7?

The following equations describe an economy. (Think of C, I, G, etc., as being measured in billions and I as a percentage; a 5 percent interest rate implies I=5).

C = 0.8 (1 – t) Y

                              t = 0.30

                              I = 1000 – 50 i

G= 500

                              L = 0.25Y – 65 i

M/P = 700

                       

  1. Derive the IS equation.

AD = C + I + G + NX

AD = 0.8 (1 – t) Y + 1000 – 50i + 500

AD = 0.8 (1 – 0.3) Y + 1500 – 50i

             At equilibrium AD = Y so

                        Y= 0.8 (1 – 0.3) Y + 1500-50i

                        Y- [0.8 (1 - .3) Y]=1500 – 50i

                        Y[1 – (0.8(1 - .3))] = 1500 – 50i

                        Y= [1/ (1- (0.8 (1- 0.3))] x (1500- 50i)

                        Y= 2.27(1500 – 50i)

                        Y= 3405 – 113.5i

  1. Derive the LM equation.

M-bar/P-bar = L

700= .25Y – 65i

0.25Y = 700 +65i

Y= 4(700 + 65i)

Y= 2800 + 260i

  1. What are the equilibrium levels of income and interest rate?

3405 – 113.5i = 2800 + 260i

3405 – 2800 = 113.5i + 260i

605= 373.5i

i= 1.62

Y= 2800 + 260(1.62)

Y= 3221.2

  1. What is the value of aG which corresponds to simple multiplier with taxes?
    1. AG= 2.27 (First question)
  2. What would be the new equilibrium levels of income and interest rate if the congress passed a tax-cut and the new tax rate was 25%, and concurrently, people became less frugal and consequently marginal propensity to consume increases to 0.90.
  3. If the increased spending overshoots and the economy starts to experience inflation, calculate the new levels of equilibrium income and interest rate if the new Federal Reserve decided to curb spending and by lowering the real money supply to 550?
  4. For each step, graph the IS and LM curves and clearly show their movements for the problems above. Although the graph needs not to be precise, you must clearly show if IS or LM curves shifted or tilted and in which direction.

1-A contractor decided to build homes that will include the middle 80% of the market. If the average size of homes built is 1750 square feet, find the maximum and minimum sizes of the homes the contractor should build. Assume that the standard deviation is 96 square feet and the variable is normally distributed.

2-Determine the indicated probability for a binomial experiment with the given number of trials n and the given success probability p. n = 13, p = 0.7, P(Fewer than 4)

3-A student takes a 5 question multiple choice quiz with 4 choices for each question. If the student guesses at random on each question, what is the probability that the student gets exactly 2 questions correct?

4- An investor is considering a $15,000 investment in a start-up company. She estimates that she has probability 0.15 of a $10,000 loss, probability 0.1 of a $10,000 profit, probability 0.3 of a $30,000 profit, and probability 0.45 of breaking even (a profit of $0). What is the expected value of the profit? $11,500 $15,250 $10,000 $8,500

Since you became an expert in Corporate Finance and CAPM, now you want to make some money by investing in stocks. Instead of buying one stock, you will make a diversified portfolio using several stocks. Suppose that there are only 3 stocks in the market, and expected return, standard deviation, and correlations are as follows

Stocks Expected Return Standard Deviation

Stock A    5% 5%

Stock B    7% 10%

Stock C 10%    20%


Correlations Stock A Stock B Stock C

Stock A 1    0.4 -0.3

Stock B 0.4 1 0.7

Stock C -0.3 0.7 1

*Calculate Expected Return and Standard Deviation of Each Portfolio:
Portfolio 1: 30% in Stock A + 70% in Stock B
Portfolio 2: 60% in Stock B + 40% in Stock C
Portfolio 3: 50% in Stock A + 50% in Stock C
