A university has 7 departments namely, IT, Finance, HR, Management, Faculty, students and R&D. The university also has an ADSL internet connection which is shared for the different departments. It is required that all the departments should have intercommunication via LAN. Each of the department contain 50-200 users.
As the case everywhere, the students and the staffs need to have access to Wi-Fi connectivity as well. The university campus contains 3 different buildings located nearby, having 2, 3 and 4 floors each. You are asked to design of a network infrastructure for a university, focusing on the following aspects.
The network architecture model you will be choosing.
The switching and routing requirement
The IP Design schema for the department.
Design with VLAN
The security measures taken for both the wired and wireless network.
The Wi-Fi design as required for the university.
The final network infrastructure may be created in packet tracer or any familiar tools available. You may create the model in a word file too, by indicating all the information clearly.

Scenario: Upon successful completion of the MBA program, imagine you work in the analytics department for a consulting company. Your assignment is to analyze one of the following databases:
Select one of the databases based on the information in the Signature Assignment Options.
Provide a 1,600-word detailed, four part, statistical report with the following sections:
Part 1 - Preliminary Analysis
Generally, as a statistics consultant, you will be given a problem and data. At times, you may have to gather additional data. For this assignment, assume all the data is already gathered for you.
State the objective:
Describe the population in the study clearly and in sufficient detail:
Discuss the types of data and variables:
Part 2 - Descriptive Statistics
Examine the given data.
Present the descriptive statistics (mean, median, mode, range, standard deviation, variance, CV, and five-number summary).
Identify any outliers in the data.
Present any graphs or charts you think are appropriate for the data.
Note: Ideally, we want to assess the conditions of normality too. However, for the purpose of this exercise, assume data is drawn from normal populations.
Part 3 - Inferential Statistics
Use the Part 3: Inferential Statistics document.
Hint: A final conclusion saying "reject the null hypothesis" by itself without explanation is basically worthless to those who hired you. Similarly, stating the conclusion is false or rejected is not sufficient.
Part 4 - Conclusion and Recommendations
Include the following:

Box-office. The Walt Disney Company, the production studio behind the Marvel Cinematic Universe, is trying to find the best release date for their new super hero movie. They are hesitating between the summer and winter holiday release, and they want to know if there is any difference between the earning potential during those seasons. The analytics division in the company examined box-office data for movies released during the past 5 years in the USA and Canada and found that 50 out of 1253 movies with summer release date earned over 400 million dollars. They also counted that out of 540 movies released in the winter, 10 earned over 400 million dollars. Round all answers to four decimal places.
| Over 400 million USD | Under 400 million USD | Total | |
| Summer release | 50 | 1253 | |
| Winter release | 10 | 540 | |
| Total |
1. We want to investigate whether there is a difference in the
proportion of movies that earn over 400 million dollars for the two
release seasons. Which hypotheses should we use?
H0H0: The variables ? Release season and Box-office USA
and Canada Release season and Year Box-office and Production
studio are ? independent not independent .
The difference in the proportions of movies that earned over 400
million dollars in the sample data ? is is
not due to chance.
HAHA: The variables are ? independent not independent .
The difference in the proportions of movies that earned over 400
million dollars ? is is not due to
chance.
2. Calculate the difference in the proportions of movies that earned over 400 million dollars: p^Summerp^Summer- p^Winterp^Winter =
3. The paragraph below describes the set up for a randomization test, if we were to conduct a hypothesis test without using software. Fill in the blanks with a number.
We write Summer on cards and cards representing the movies with summer release date, and Winter on cards. Then, we shuffle these cards and split them into two groups: one group of size representing the movies with box-office over 400 million dollars, and another group of size representing the rest of the movies. We calculate the difference in the proportions of movies that earned over 400 million dollars during the two release seasons to get p^Summerp^Summer- p^Winterp^Winter. Finally, we build a histogram of these simulated differences. Use the Two Proportion Resampling Test app embedded below to do this.

You are a systems analyst contracted by Earth Friendly Babies, a mail-order company that sells earth friendly baby products. You and your consulting firm have recently completed development of a new system for managing orders and inventory for Earth Friendly Babies. System architecture already has been decided, and you are ready to embark upon installation, evaluation, and training for the new system. Earth Friendly Babies has grown from an at-home business set up by a stay-at-home mom to a small mail-order company that sends out catalogs to 10 states, employs 5 people in addition to the business owner, and has office and warehouse space in an office park designed to encourage small businesses. The business has relied upon manual data collection methods for taking orders, billing, and managing inventory. The new IS will provide the support necessary for the company to expand to all 50 states with their mail-order campaign. None of the employees has worked with an IS system similar to the one designed. All employees need to be trained in all aspects of the new system, because the company at this point relies on its employees to work where needed, rather than at one job only. You need to provide training for inventory/warehouse and for order support. Each individual will require nine hours total of training, broken down into three three-hour modules, and two people can be released from work at a time for training.
1. Design two training schedules for the new system — one which is based upon two
people released from work at a time, and one which takes advantage of the small number of employees that need to be trained.
2. Develop a training budget assuming that the trainer is paid $140 per hour, that 8 hours are needed to develop training materials, and that the 5 workers earn $18
per hour including overhead. Present the alternatives in memo form to the business owner, and identify any additional information that should be taken into
account when choosing between the two training schedules.
3. Prepare a memo detailing which changeover method you are recommending, and why.
4. Should Earth Friendly Babies perform a post-implementation evaluation? If your answer is no, justify. If yes, who should perform it?

Receivables can also be used to analyze the financial health of a company. Research the Accounts Receivable Turnover ratio for TWO companies in the same industry. Report back the ratios for these companies. Analyze these ratios and tell us, based only on this information, what company is in a better financial position. Is this what you expected, why or why not?

A company pays its employees as managers (who receive a fixed weekly salary), hourly workers (who receive a fixed hourly wage for up to the first 40 hours they work and “time-and-a-half,” i.e. 1.5 times their hourly wage, for overtime hours worked), commission workers (who receive $250 plus 5.7% of their gross weekly sales), or pieceworkers (who receive a fixed amount of money per item for each of the items they produce-each pieceworker in this company works on only one type of item). Write a program to compute the weekly pay for each employee. You do not know the number of employees in advance. Each type of employee has its own pay code: Managers have pay code 1, hourly workers have code 2, commission workers have code 3 and pieceworkers have code 4. Use a switch to compute each employee’s pay based on that employee’s pay code. Within the switch, prompt the user to enter the appropriate facts your program needs to calculate each employee’s pay based on that employee’s pay code.
I was wondering how I could get the sample output to be like this as seen below:
The sample output should be like this:

Betty Vinson was the director of management reporting at WorldCom. She had worked there for five years when the fraud was uncovered and received two promotions during that time. Vinson’s salary increased from $50,000 when she started to $80,000 in 2002. Vinson reported to Buford Yates, director of general accounting, who reported to David Myers, senior vice president and controller, who then reported to CFO Scott Sullivan. (See Figure 1 for an organizational chart.) A hard worker who often stayed late or brought work home, Vinson considered herself lucky to land the job at WorldCom, as it was located in her hometown of Clinton, Miss. Vinson graduated from Mississippi College in 1978 and married her college sweetheart, Tom Vinson, a printing-equipment salesman who earned $40,000 a year. The couple had one daughter and lived a typical suburban lifestyle. Prior to working at WorldCom, Vinson worked as an accountant for various banking enterprises in Louisiana and Kansas City from 1978 to 1996. She also earned the Certified Public Accountant (CPA) credential during that time.
Problems began to emerge in the telecommunications industry in the late 1990s. The industry had over expanded, and every company was beginning to feel the effects, including WorldCom. By 2000, WorldCom’s expenses were increasing faster than revenues. In September 2000, WorldCom had to find $828 million to meet earnings targets expected by Wall Street. Vinson and her accounting colleagues found $50 million, but it wasn’t nearly enough. Senior management instructed her and her accounting coworkers to reduce reserve accounts for line costs to cover this shortfall. Reserves had been set aside based on estimates of potential losses, but they needed to have enough reason to reduce the reserve. Meeting earnings targets wasn’t a valid reason. Sullivan pressed Myers and Vinson’s boss, Yates, to make this adjustment. Yates told his accounting team that he had reservations, too, but that Sullivan promised this was a one-time adjustment. They all agreed to go along with the accounting adjustment. Vinson felt uncomfortable with this and considered resigning. The corporate accounting department’s discomfort with the entries prompted Sullivan to call the accountants into his office. He used an analogy that WorldCom was an aircraft carrier, and they needed to land the planes that were in the air. He urged them to wait until the planes had landed, and then they could leave the company if they still wanted to. Sullivan assured them that nothing they would do was illegal and that it wouldn’t be repeated. After talking to her husband, Vinson decided against resigning because of her family’s dependence on her salary and health insurance. In April 2001, the gap in meeting earnings targets was $771 million. The reserve pools weren’t large enough to cover this gap. Sullivan’s new strategy was to shift line costs, recorded as expenses, to capital expenditure accounts. Yates objected. Sullivan insisted it was the only way to cover this gap. Vinson and her coworker both felt cornered; this was clearly fraudulent accounting. The only choices now were to resign or make the entries. The three-person accounting team identified the capital accounts to use, and Vinson made the entries to transfer the $771 million. She backdated entries to February in the computer system and then indicated to colleagues at WorldCom that she was going to look for another job. These entries continued quarterly through April 2002. The Securities & Exchange Commission (SEC) was informed of the problem in June 2002 as a result of the efforts of the WorldCom internal audit team. The SEC would ultimately charge CFO Scott Sullivan, Controller David Myers, and accountants Buford Yates, Troy Normand, and Betty Vinson. According to the SEC complaint: “At the direction of WorldCom senior management, Vinson and other WorldCom employees caused WorldCom to overstate materially its earnings in contravention of generally accepted accounting principles (GAAP) for at least seven successive fiscal quarters, from as early as October 2000 through April 2002. Vinson knew or was reckless in not knowing, that these entries were made without supporting documentation, were not in conformity with GAAP, were not disclosed to the investing public, and were designed to allow WorldCom to appear to meet Wall Street analysts’ quarterly earnings estimates
Paraphrase one of Yates’ arguments?
This argument best describes the ____________________________________ “reason and rationalization” of GVV because?
In response to Mr. Yate’s argument, Betty and Troy could have countered?
