Write a program that reverses a text file by using a stack. The user interface must consist of 2 list boxes and 3 buttons. The 3 buttons are: Read - reads the text file into list box 1. Reverse - reverses the items in list box 1 by pushing them onto stack 1, then popping them from stack 1 (in the reverse order) and adding them to list box 2. Write - writes the contents of list box 2 to a new text file. At first, only the Read button is enabled. After it is clicked, it is disabled and the Reverse button is enabled. After it is clicked, it is disabled and the Write button is enabled. After it is clicked, it is disabled. The name of the input text file is "input.txt". The input text file will contain no more than 100 lines of text. This fact is not needed by the program. It simply means that memory usage is not an issue. The name of the output text file is "output.txt". Notes: 1. The name of your main class should be ReverseFileViaStack. 2. Use the Java class library Stack class for your stack. 3. Use a border layout for your contents pane. 4. In the north region include the following title: Reverse a Text File via a Stack. 5. Use a panel in the center region to contain the 2 list boxes (side-by-side). 6. Place the 3 buttons in the south region. 7. A useful resource for this project is the week 5 video: Java GUI List Components

Implement a priority queue using a DoublyLinkedList where the node with the highest priority (key) is the right-most node.
The remove (de-queue) operation returns the node with the highest priority (key).
If displayForward() displays List (first-->last) : 10 30 40 55
remove() would return the node with key 55.
Demonstrate by inserting keys at random, displayForward(), call remove then displayForward() again.
You will then attach a modified DoublyLinkedList.java (to contain the new priorityInsert(long key) and priorityRemove() methods), and a driver to demonstrate as shown above.

Use the provided PQDoublyLinkedTest.java to test your code.

public class PQDoublyLinkedTest
{
    public static void main(String[] args)
    {                             // make a new list
        DoublyLinkedList theList = new DoublyLinkedList();

        theList.priorityInsert(22);      // insert at front
        theList.priorityInsert(44);
        theList.priorityInsert(66);

        theList.priorityInsert(11);       // insert at rear
        theList.priorityInsert(33);
        theList.priorityInsert(55);
        
        theList.priorityInsert(10);
        theList.priorityInsert(70);
        theList.priorityInsert(30);

        theList.displayForward();     // display list forward
        Link2 removed = theList.priorityRemove();
        System.out.print("priorityRemove() returned node with key: ");
        removed.displayLink2();
        
    }  // end main()
}  // end class PQDoublyLinkedTest

3. Plot the below scores using the most appropriate type of graph. The goal is to see how these bowlers have performed over time.

4. Plot the scores below for the bowler's scores as a function of their ages. The goal is to see a relationship between two variables...scores vs. ages. Also, create a list according to their ages (oldest first), then their scores (highest first), then their names (alphabetically).

5. Graph the percentages of the students at a college:
         Freshmen = 40%, Sophomores = 30%, Juniors = 20%, Seniors = 10%

6. Make a spread sheet that calculates your grades in this class.

You are studying to enter professions that require high moral and ethical behavior. Your commitment to such standards should begin in this class and continue through every class in your graduate degree program. This week's discussion questions:
1) Why ethics and professional conduct are so important in the accounting professions, and
2) Why behaving ethically in your graduate studies is critical to your goal to graduate and work in the accounting industry.

Some major professional accounting associations/organizations include:

American Accounting Association

American Institute of CPA's

American Society of Women Accountants

American Taxation Association

Association of Certified Fraud Examiners

Association of Government Accountants

Chartered Global Management Accountants

Information Systems Audit and Control Association

Institute of Internal Auditors

Institute of Management Accountants

Institute of Industrial Accountants

Insurance Accounting and Systems Association

International Association of Accounting Education

National Association of Black Accountants

National Society of Accountants

Professional Association of Small Business Accountants

Professional Accounting Society of America

Your state" Society of CPA's

Questions to spark class discussion:

Randomly select one of the professional accounting organizations from the list below.

Summarize and discuss the professional code of ethics of the organization you selected.

Identify a few of the key codes and or responsibilities of ethical and professional conduct in this organization.

Discuss their importance and how you, as students can model these behaviors.

As an IT manager, it is imperative to know how well the company you work for is performing overall. This is especially important in order to ensure that the IT operations deliver on supporting the organizational vision and business strategy. Therefore, students will evaluate the factors involved in making the IT department a profit center, especially considering the market's current focus on analytics. First, conduct research to acquire the income statements (also referred to as profit and loss or P&L statements) of any two organizations that have a prominent IT department. Many examples of such organizations are highly publicized and can be located with a general online search for the list of "Fortune 500 companies." You may also utilize the income statements from your own company or a company where you have previously worked. If you decide to include the latter, please use anonymous references for your proposal submission and not include the name of the company. Once the income statements for the two organizations with a prominent IT department have been identified, complete a 250-500 word review with the following components: An analysis of the profitability of the company over various periods of time: monthly, quarterly, or annually. Include a description of the overall areas of success (profits) and any challenging areas (losses). A narrative description of the impact of the P&L on the IT department. Include the specific or potential factors involved in each organization's ability to generate revenue involving IT. A description of the potential methods for reducing IT expenses.

1. Life Expectancy Part 3 Refer to the Data Set AllCountries. (Data sets can be found near the bottom of the Read, Study & Practice section of WileyPLUS.) Use the 199 life expectancies listed and StatKey to answer the following questions.

a. Use an equation editor to formulate the null and alternative hypothesis to test the following claim:

“The average life expectancy for all countries is not 68.9 years.”

b. From the AllCountries data, do your best to randomly select 10 of the 213 life expectancies listed. List the 10 values you selected below. (You can use the 10 values from Graded Problem Set 3 if you’d like.)

Bermuda:80.6

Bulgaria: 74.5

Egypt, Arab Rep.: 71.1

Kora Rep: 81.5

Argentina: 76.2

Panama: 77.6

Canada: 81.4

Korea, Dem. Rep.:69.8

Belarus: 72.5

Belize: 73.9

c. Construct a randomization distribution in StatKey to test the above hypothesis. Take at least 1000 samples. Take a screenshot of your StatKey page, and paste it below. (Your graph will differ from other students.)

d. Find and interpret the p-value in regards to the hypothesis and claim.

I have randomly selected the 10 life expectancies from the data set and hopefully, you don't need anything else from the dataset

Suppose that you are the CEO of a discount airline that caters to students on tight budgets who want to travel to warm locations when the weather gets cold. Currently, your airline flies small regional jets from the MBS International Airport to 6 cities in Florida. Assume that your airline has a monopoly on the local market.

1. List the conditions that apply to monopolies, and briefly describe how they apply to this airline. (6 points)
2. Using the table below, determine the profit maximizing number of passengers that you should serve out of the MBS market. The price is for a round-trip ticket. (8 points)

3. Suppose that your fixed costs are $50,000, and your variable costs are $100 per passenger. Would you ever consider shutting down the airline? At what point would you do this and why? (8 points)

3. Suppose that your airline was competing with 3 other airlines for the passengers wanting to fly to Florida. How would you determine what fare to charge? Would you collude with your competitors? Why or why not? (8 points)

Case one:
Intergovernmental working group of experts on international
standards of accounting and reporting
1. What are International Financial Reporting Standards (IFRS)?
2. Many concerns are expressed in this article. List three factors that you think
are causing concern about the impact of adoption of IFRS.
3. Consider each of the three factors you mentioned in response to question 2.
(a) Is there empirical evidence to support the factor?
(b) Is the analysis leading from the factor to the concerns about adoption
of IFRS scientific or naturalistic in its approach? Explain your answer.

Case two:
1. On 1 January 2005 Australia adopted IASB standards.
(a) Do you agree with this change? Why or why not?
(b) Who stands to gain from Australia’s adoption of IASB standards?
Explain.
(c) Who stands to lose from Australia’s adoption of IASB standards?
Explain.
From 1 January 2005 the AASB will issue Australian equivalents to IFRS.
This process involves the AASB issuing IASB exposure drafts as exposure
drafts in Australia. Constituents can provide comments on standards to the
AASB and IASB. Final standards issued by the IASB are subsequently
issued in Australia with any additional paragraphs necessary to make the
standards suitable for public sector and not-for-profit entities.
Requirement:
Students are required to answer questions in an essay format (introduction, body,
conclusion

You have been appointed as the Software Quality Assurance Manager for a
project that enables students to access their results on their android phones.

As the person responsible for the overall quality aspects, its your interest to
ensure that strong quality assurance practices are put in place to forestall any
software failure by the end-users.

i. It is important that you conduct requirements validation as part of your
quality assurance practices in this project. Could you explain in your own
words, what is requirements validation and its importance? What is the
impact if this process is not well conducted?

ii. Requirements review is one of the requirements validation techniques
in quality assurance. If you are going to make requirements review, which
method do you prefer to do the activity, formal or informal method?
Explain why you choose the method. Suggest and explain the types of
checks that should be done on the requirements in the software
requirement specification.

b. You are investigating systems requirements for a shipping company. Assume
that you have set up an interview with the manager of the shipping
department. Your objective is to determine how shipping works and what the
information requirements for the new system will be.
