An automobile rental company wants to predict the yearly maintenance expense (Y) for an automobile using the number of miles driven during the year ( X1 ) and the age of the car ( X2 , in years) at the beginning of the year. The company has gathered the data on 10 automobiles and the regression information from Excel is presented below. Use this information to answer the following questions.

Summary measures Multiple R 0.9689 R-Square 0.9387 Adj R-Squared 0.9212 StErr of Estimate 72.218

a. Use the information above to write out the estimated linear regression model.

b. Interpret each of the estimated coefficients of the regression model in part (a).

c. Identify and interpret the coefficient of determination ( R2 ) and the adjusted R2 .

d. Does the given set of explanatory variables do a good job of explaining changes in the maintenance costs? Explain why or why not.

Which of the current asset management category, as a finance manager would you focus on and why?

Create a Matlab program to load in the attached file File_Q5_Use.csv. You will first need to click on the link to open it, then save it as a .csv file in the directory you are using in your Matlab programs before you can load it in to Matlab.

It has 2 columns, the first column is the x values, the second column is the y values. Set Figure (1). Plot the points using red stars and a blue line with a title of 'Original Points' and get a general idea of what the degree of the polynomial is. It might be easier to split the matrix into 2 vectors x_vec and y_vec.

From the graph - where approximately are the real zeros of this polynomial? Does this polynomial appear to be ODD or EVEN. ? Answer the questions in the %RESULTS.  

After this plot, set Figure (2) to get a different Figure window open but so that the old figure window does not close.

Next, use POLYFIT to find the polynomial that fits the data [Hint: it is less than degree 8 and more than degree 1]. Use a FOR loop to cycle through the from n = 2:1:7 and do the following on each loop:

a. Find using POLYFIT, the polynomial for each degree of n. Do NOT suppress the values of the coefficients returned by each pass through the FOR loop.  

b. Using SUBPLOT where n is the location, plot on the same graph, the original points using red stars and the polynomial created by POLYFIT using a range of [-3:0.1:3] using a blue line. Make a title for each subgraph showing the degree of the polynomial fitted.  

Based upon the 6 graphs, which do you think is the correct degree of the polynomial? Answer in %RESULTS.

The basis for this polynomial was: 2x^5 - 3x^4 + 2x^3 -3x^2 - 144x + 216 = 0. Create a Figure 3 which plots the original points in red stars and points from this polynomial in a blue line for a range of [-3 : 0.1 : 3 ].  

Looking at the graphs, how many data points appear to be outliers, i.e. they probably should not be used in the graph? Answer in %RESULTS.

Looking at the graphs, the plots for degree 5, 6, 7 all appear to be almost the same. Switch to full screen to examine Figure 2. Remembering that the line of best fit passes through as many points as possible and minimizes the distances between the line and the points, can you determine by eye which degree of 5, 6, or 7 would be best?

Part II.

Suppose there are students living in two dorms, called Gold and Blue. Students are each one of two types, Partiers and Studiers, which determines their preferences. Each dorm will vote on a tax rate, the proceeds of which will be used to fund a party. The mean of the votes will become the effective tax rate, and all residents of the dorm will be required to pay that fee. To simplify the problem, assume that all people may vote for either a tax of $0 or a tax of $100. (For example, if half of all people vote for $100 in a dorm, then the tax rate will be $50. The tax rate must be between $0 and $100.)

All students have a payoff (utility) equal to (1000−T)+μ(N ×T)

where T is the tax that they pay, and N is the number of people living in the dorm (so N × T is the total money spent on the party). The parameter μ is 0 for Studiers and 0.2 for Partiers.

Suppose that there are 100 Partiers and 100 Studiers. Initially, there are 70 Partiers and 30 Studiers in Gold Dorm, with the remainder in Blue. Given that allocation of people, what will be the tax rates in Gold and Blue? (2 points) (There will be two different tax rates.)

1. What is the total utility (payoff) in society (i.e., add up the payoff of all 200 students)?

2. Suppose now that people can move and sort. Suppose further that people choose where to go assuming that the tax rate and party size tomorrow is the same as it was yesterday. What will be the new tax rates in Gold and Blue after people sort?

3. What is the total utility (payoff) in society (i.e., add up the payoff of all 200 students)?

Scenario:
You have recently gained employment as a Trainee Engineering Manager with a large multinational company which manufactures electrical machines and transducers, including transformers, motors, generators, sensors and actuators.
Your line manager has tasked you with creating a report to indicate your level of knowledge in engineering management.

Activity
You have specifically been instructed to provide written solutions to the following question.

a) Compare a range risk management practices and quality management theories and identify how they can improve management processes within the engineering industry? Which activities will improve management strategies? How do you think management strategies may be improved in certain circumstances or situations?

Give a brief summary of the stakeholder theory of corporate responsibility as outlined by Freeman in both his essay and the video segments we watched on this issue. Briefly, what is the legal argument and the economic argument for the stakeholder view? Who are Two of the stakeholders that Freeman notes explicitly has having rights that must be considered by corporate executives, other than stockholders? As one example, explain why Freeman thinks that one of these groups has an investment in the company that gives the executives the fiduciary duty to consider their well-being in corporate decisions.

Everyone knows what money is. It is the collection of coins and bills that we carry around in our pockets, purses. and wallets. Or at least that people often think that is what money is? In fact, “money” is merely a “social convention” as described by the text – Money is “what it does” rather than “what it is.”

i.     (1) Briefly describe three (3) of the four (4) functions that must be present to make money, well, money, AND; (2) It is often debated whether “crypto-currencies” such as BitCoin or Ethereum or perhaps the forthcoming “Libra” from Facebook, actually are “money?” WHICH “function” of money causes the biggest question for these crypto-currencies and WHY is this the case?

A hollow sphere of radius 0.190 m, with rotational inertia I = 0.0218 kg·m² about a line through its center of mass, rolls without slipping up a surface inclined at 10.8° to the horizontal. At a certain initial position, the sphere's total kinetic energy is 7.90 J. (a) How much of this initial kinetic energy is rotational? (b) What is the speed of the center of mass of the sphere at the initial position? When the sphere has moved 0.600 m up the incline from its initial position, what are (c) its total kinetic energy and (d) the speed of its center of mass?
