Question 3: (Minitab or Excel – Excel is easiest)

The table below shows the average distance of each of the nine planets from the sun, and the length of the year (in earth years). Note that Pluto is not considered a planet anymore (check it out on Wikipedia).

a) Plot the Length of the Year (the response) versus the Distance from the Sun (the explanatory variable). Describe the scatterplot.

b) Fit a linear model that will help predict the Length of Year a planet from its Distance from the Sun. Does the model provide a good fit?

c) Produce the residual plot for the model you developed in 3b. The plot shows a clear trend. Describe it. We are going to improve the model by re-expressing both distance and length of year in the logarithmic scale. This approach is indicated by the large amount of variance in both variables as well as strong positive skewness of their distributions (you can check both of these facts for yourself by making stemand-leaf plots and obtaining summary statistics—no need to include this step in your paper).

d) Take the base ten logarithm of the distance and length of year variables. We will refer to the new variable as the Log(distance) and Log(length). Follow the Minitab directions below on how to proceed.

e) Fit a regression line to predict Log(length) from Log(distance).

f) Obtain the residual plot for the model.

g) Did we improve the model?

You have recently been hired by Layton Motors, Inc. (LMI), in its relatively new treasury management department. LMI was founded eight years ago by Rachel Layton. Rachel found a method to manufacture a cheaper battery that will hold a larger charge, giving a car powered by the battery a range of 700 miles before requiring a recharge. The cars manufactured by LMI are midsized and carry a price that allows the company to compete with other mainstream auto manufacturers. The company is privately owned by Rachel and her family, and it had sales of $197 million last year.

LMI primarily sells to customers who buy the cars online, although it does have a limited number of company-owned dealerships. The customer selects any customization and makes a deposit of 20 percent of the purchase price. After the order is taken, the car is made to order, typically within 45 days. LMI's growth to date has come from its profits. When the company had sufficient capital, it would expand production. Relatively little formal analysis has been used in its capital budgeting process. Rachel has just read about capital budgeting techniques and has come to you for help. For starters, the company has never attempted to determine its cost of capital, and Rachel would like you to perform the analysis. Because the company is privately owned, it is difficult to determine the cost of equity for the company. Rachel wants you to use the pure play approach to estimate the cost of capital for LMI, and she has chosen Tesla Motors as a representative company. The following questions will lead you through the steps to calculate this estimate.

7. You used TSLA as a pure play company to estimate the cost of capital for LMI. Are there any potential problems with this approach in this situation and why?

Please provide steps.

For a random sample of 20 automobile models, we record the value of the model as a new car and the value after the car has been purchased and driven 10 miles.¹ The difference between these two is a measure of the depreciation on the car just by driving it off the lot. Depreciation values from our sample of 20 automobile models can be found in the dataset CarDepreciation.

With the majority of health-care costs spent for the treatment of chronic diseases (High BP, Dibetes & HIV) and the reason for most emergency room visits being non-emergencies, the time is ripe for telemedicine in South Africa. More so with Covid-19 pandemic, patients are reluctunt to visit a hospital for non-emergencies. Patients are using their phones, tablets, and keyboards instead of making an office visit or trip to the emergency room. Technology makes it possible for doctors to consult with patients through Skype or FaceTime on smartphones, access medical tests via electronic medical records, and send a prescription to a patient’s local pharmacy—all from miles away. The telemedicine industry is still in its infancy, earning only $868 million in annual revenue in 2017, but it is predicted to increase to an almost $56 billion industry by 2023. It is expected to exhibit a CAGR of 17% from 2018 to 2023 (forecast period). Technology isn’t the only reason for this industry’s growth such as adoption of electronic health records (EHR) by hospitals is one of the primary drivers of the market. The legislation suport by Governements that are encouraging electronic medical records is also adding fuel to this fire. In order to ensure health care services are still being provided during the national period of shut down and during the Covid- 19 pandemic and to achieve the objectives of “The Allied Health Professions Act” (63) was amended on 25 March 2020 by President Cyril Ramaphosa that allows to practice telehealth and/or telemedicne for medical professionals.

Based on the scenario given above, critically discuss pros and cons of offering medical services with help of telemedicine. Critically discuss the marketing decisions that may be used in the selected product life cycle of telemedicine? Critically evaluate the role of mobile technology and artificial intelligence (AI) in the evolution of this industry and predict future trajectory? Justify your response.

Jerry is a 30-year-old male and is the youngest of three sons. He grew up in a suburb of

Chicago and lives 10 miles from his childhood home. He recalls his early family life as unhappy.

He perceived his parents’ marriage as miserable and unfulfilling. He recalls that his father

(who died two years ago) never approved of his interests and that his mother was unhappy

and would frequently complain about the fact that she had no female children.

Jerry has just been laid off from his job working for an innovative software company. Recently,

he has been doing some freelance work in programming, but he is barely making ends meet.

He has been in a serious and exclusive relationship for the past six months with a female coworker,

who has not yet been laid off from the software firm. Lately he has been avoiding

spending time with her, as she has been complaining about his irritability and negativism

about his future job prospects.

Jerry notices that he is having some trouble controlling his drinking, especially when he is

alone at the end of the day. This problem has been of such magnitude that he is considering

seeking counseling related to his substance use.

Boyne University offers an extensive continuing education program in many cities throughout the state. For the convenience of its faculty and administrative staff and to save costs, the university operates a motor pool. The motor pool’s monthly planning budget is based on operating 19 vehicles; however, for the month of March the university purchased one additional vehicle. The motor pool furnishes gasoline, oil, and other supplies for its automobiles. A mechanic does routine maintenance and minor repairs. Major repairs are performed at a nearby commercial garage.

The following cost control report shows actual operating costs for March of the current year compared to the planning budget for March.

The planning budget was based on the following assumptions:

1. $0.22 per mile for gasoline.
2. $0.11 per mile for oil, minor repairs, and parts.
3. $46 per automobile per month for outside repairs.
4. $81 per automobile per month for insurance.
5. $8,610 per month for salaries and benefits.
6. $206 per automobile per month for depreciation.

The supervisor of the motor pool is unhappy with the report, claiming it paints an unfair picture of the motor pool’s performance.

Required:

1. Calculate the spending variances for March. (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values.)

Using the provided case study (“Why Illegal Immigration Is an Intergovernmental Mess and Will Remain So” in Chapter 4 of the textbook), craft a paper analyzing the issues at play through the lens of public-administration theory and ethics. Specifically consider: What are the issues and perspectives related to immigration in the United States? How is immigration policy developed and what factors impact its development? What concepts in public administration would guide the actions of a public agent charged with enforcing the law? Specifically, you must address the critical elements listed below.

I. Overview: In this section, outline the issues related to immigration in the United States by briefly explaining the context and perspectives related to legal and illegal immigration in the United States.

II. Policy Development and Enforcement: In this section, analyze how immigration policy is developed and the variables that impact its enforcement. A. Discuss the political, social, economic, and cultural variables that impact public policy in immigration reform. B. Analyze ethical expectations of public administrators (such as border-patrol agents) charged with enforcing laws or policies that have been developed, especially in light of intense public opinion or scrutiny.

III. Situational Response: In this section, imagine you are a border-patrol agent. How would your role impact your ability to defend and advocate for your personal opinion on immigration? A. Defend your position on whether public-agency employees give up certain First Amendment rights by virtue of serving in their positions. B. Explain how Miles Law applies in this situation. C. Explain how organizational-culture theory could influence your actions as a border-patrol agent. D. Describe the ways that you could advocate to change the law without breaking it as a border-patrol agent.

Write a C# code that creates objects and classes with their member functions for KrisFlyer,
a Singapore Airlines Loyalty program. You are asked to write an inheritance hierarchy discount
system that benefits KrisFlyer members program to calculate their profit.

A brief about KrisFlyer is that it is useful for those who fly on Singapore Airlines (its
partners like Virgin Australia and Air New Zealand) frequently. KrisFlyer miles can be earned
through credit cards, flying and bonus miles promotions. The miles can be redeemed for award
flights in all categories. It has three types of memberships namely Basic, Elite Silver and Elite
Gold. When registered for the first time, all the customers get instant access to the basic

membership level of KrisFlyer. In 2020, Singapore Airlines offers a flat 10%, 20% and 30%
discount to its Basic, Elite Silver and Elite Gold members respectively for all services provided.
Customers without membership receive no discount. The students have to implement basic OOPs
concepts such as inheritance, polymorphism and encapsulation.
Inheritance
Base class: Create an inheritance hierarchy to represent various types of memberships. Use
KrisFlyer as the base class of the hierarchy, then include derived classes Basic, Elite Silver and
Elite Gold that deriver from KrisFlyer. Base class KrisFlyer should have data members
representing name, membership, flight, price for flight, number of passengers for the members.
The constructor should initialize these data members. Ensure that flight price and number of
passengers contain positive values. KrisFlyer should include a public member function
calculateCost() that returns a double indicating the cost by multiplying the price for flight by the
number of passengers.
Derived class: Basic, Elite Silver and Elite Gold should inherit the functionality of base
class KrisFlyer, but also include a data member that represents a discount that the reward program
has offered recently. All the derived class’s constructor should receive a value to initialize this data
member. In 2020, Singapore Airlines offers a flat 10%, 20% and 30% discount to its Basic, Elite
Silver and Elite Gold members respectively for all services provided. All the derived members
should redefine calculateCost() so that it applies the discount to the booked flights. It shall compute
the total bill if a customer purchases y tickets for a price of $x for each flight for their visit using
Krisflyer.
Your system shall consist of four classes: 1. KrisFlyer (base class), derived classes
including Basic, Elite Silver, Elite Gold.
Polymorphism
Implement a method display() that displays all the records of the system. Another form of
the method display(string cust_name) that displays records related to the customer name passed in
the argument.

Encapsulation
Define the instance variables private/ public so that they cannot/can be accessed from
outside the class. Implement getter and setter method for the variables in the program.
Write a program that implements basic Object-oriented concepts including encapsulation
polymorphism and inheritance. Also, the program is expected to get the basic input from the user
based on either console/Desktop.
The student is expected to do the following tasks:
1. Draw the class diagram of the given scenario
2. Write the c# classes with suggested data members and functions
3. Write the base and derived classes for implementing inheritance in the program.
4. Implement polymorphism and encapsulation to check for accessibility of data members
and different form of the data member
5. Write the main logic that takes input from the user members with their bookings
6. Write the code to display the output as displayed (it is a sample)
Expected output

The given output is a sample. The student is free to use creative ideas to display the output of the
program. It needs to be an interactive session where the user feeds in dynamic information.
