Use the Chi-Square option in the Nonparametric Tests menu to answer the questions based on the following scenario. (Assume a level of significance of .05 and use information from the scenario to determine the expected frequencies for each category).
Scenario: During the analysis of the district data, it was determined that one high school had substantially higher Graduate Exit Exam scores than the state average and the averages of high schools in the surrounding districts. To better understand possible reasons for this difference, the superintendent conducted several analyses. One analysis examined the population of students who completed the exam. Specifically, the superintendent wanted to know if the distribution of special education, regular education, and gifted/talented test takers from the local high school differed from the statewide distribution. The obtained data are provided below. Description Special Education* Regular Education Gifted/Talented Number of students from the local high school who took the

VideoDev Ltd is a video and production development company which works for clients across Australia and New Zealand. The company is considering moving some of its computer infrastructure into the Cloud. The VideoDev Board is contemplating this move as a way to increase the company’s flexibility and responsiveness, as well as to achieve some savings on the cost of maintaining their ICT infrastructure.
VideoDev has engaged you as a consultant to advise them on the use of Cloud Computing in their daily operations. They have some 100 video production, engineering and support staff that work on different projects for clients in Australia and New Zealand. They have been advised that a move to using a Cloud based infrastructure would be an advantage to them.
VideoDev have a number of application servers in their Sydney and Melbourne datacentres that provide video processing capabilities for their staff. These servers are quite heavily customised and run reasonably heavy workloads while doing video processing. There is often a considerable queue of jobs waiting to be processed, which causes backlogs in getting jobs completed on time. The Board hopes that a move to a cloud based operation may help to relieve these backlogs.
Another of VideoDev’s initial projects is to provide all their staff with a Standard Desktop Operating Environment (SDOE) on their desktop. This would include providing a standard desktop to any device that their staff may be using, as well as access to office automation, such as email, word processing, spreadsheet capabilities, as well as online storage for their files. The Board want the SDOE to be available on any device that their staff use, whether they are in the office, at home, or deployed at a customer’s office in the field.
VideoDev is considering the use of either Amazon WorkSpaces (https://aws.amazon.com/workspaces/) or Windows Virtual Desktop (https://azure.microsoft.com/en-au/services/virtual-desktop/) as a replacement for their existing desktop environment.
1. Explain how you think that VideoDev could move their video
processing to the cloud. You will need to discuss:
a. Explain the differences between the service models IaaS and PaaS
b. What type of service model you would recommend?
c. What are the advantages of, and the issues with, the service
model that you recommended for VideoDev’s video processing?
d. What other types of architectural patterns could be used in this
deployment?
e. How that move would assist in removing backlogs?

Project Details
John and Jane Doe are newlyweds with executive track careers at ACME Gadget Company. In five years, the Does would like to have a family, envisioning two young children, Jack and Jill. With an eye for the future, John and Jane are now looking to ensure that their future family has a place to call home, that their future children will have access to all the education they desire, and that they themselves will be able to enjoy retirement when the time comes. As such, they’ve come to your financial planning company for advice for purchasing a house, planning for retirement, setting up a RESP and for your perspective on a side venture. They’ve provided you with the background and questions below.
Purchase of a new home
John and Jane had planned to save $60 000 dollars over the next five years as a down payment on a house. Jane assured John that if they contributed $1000 each month to a savings account that pays an annual rate of interest of 2.5% compounded monthly that they would have enough money to put a down payment of $60 000 on their new house. Wanting their daughter to have a house, Jane’s parents (The Henrys) have offered to lend John and Jane $65 000, which they have suggested (perhaps naively) John and Jane pay back by contributing to a savings account in the Henrys’ name as per Jane’s original savings plan. John’s worried this is not fair to his in-laws. Is he correct? If so, devise a fair repayment plan that would see the Henrys repaid at a rate of 2.5% compounded monthly over the 5 years.
The Does have qualified for a mortgage of $500,000 to be amortized over 25 years. Their mortgage broker has offered them the following options:
Prime is currently at 1.5% and projected to increase by 0.25% every year for the next 10 years. Which Mortgage terms should they accept given that their goal is to pay as much principle as possible over the next 10 years?

Assignment Description
A pirate needs to do some accounting and has asked for your help. Write a program that will accept a
pirate’s starting amount of treasure in number of gold pieces. The program will then run one of two
simulations, indicated by the user:
1) The first simulation runs indefinitely, until one of two conditions is met: the pirate’s treasure
falls to 0 or below, or the pirate’s treasure grows to 1000 or above.
2) The second simulation runs for a number of years set by the user.
For both simulations, each year the pirate has an equal chance to either gain or lose 50 gold pieces. At
the end of each year, the pirate’s total gold and the year is displayed to the user. Validate all user input.
Tasks
1) The program needs to contain the following
a.
A comment header containing your name and a brief description of the program
b. At least 5 comments besides the comment header throughout your code
c.
A prompt for the starting treasure amount
d. A prompt to choose a simulation
i. The first simulation continues until the treasure amount becomes 1000 or more
or 0 or less
ii. The second simulation will prompt the user for number of years, then simulate
that many years. The gold amount can go below zero
e. For both simulations, treasure amount has an equal chance to increase by 50 or
decrease by 50 each year
f.
Output the year and treasure amount after each year
g.
“Press enter to continue” and Console.ReadLine(); at the end of your code
h. Validate all user input. Either through exception handling or boolean logic.
2) Upload a completed .cs file onto the Assignment 5 submission folder and a word document
containing the following six (6) screenshots:
a.
One run of the first simulation, starting amount 500

Windwave Ornamental Grass Company (WOGC) has been in business for forty years. The business was started by George Reed as a small producer of ornamental grass used for soil erosion and to provide a maintenance-free ground cover along highway medians and banks. Windwave focuses on two types of grass: Fireweed and Blue Haze. When motorists pass by an area planted in Fireweed, they see a tall grass that resembles embers glowing as the red-bladed grass waves in the wind. Fireweed always garners top prizes for its unique color and hardiness at ornamental grass competitions. Blue Haze on the other hand is Windwave’s sleeper. Blue Haze is a low growing variety that does well in colder climates. When seen along the highway, Blue Haze resembles a blue-gray rolling carpet.
George has seen substantial growth since WOGC’s early days when he developed and propagated each variety of grass himself. With the help of his sons, Paul and Jared, he planted and tended to his stock and created well-thought out marketing materials to introduce the varieties to local and state transportation agencies. Slowly word got around and sales began to climb.
Now, Paul and Jared each supervise a crew of field workers. Paul stood over his workers and was not shy about letting his workers know what needed to be done and how to do it. He wants things done his way and didn’t any pushback from his workers. Jared believes the people doing the work could have helpful ideas to improve efficiency. He was often found working alongside his workers from the start of a job until it is finished.
WOGC wanted to expand the nursery to increase production of Blue Haze and move into new northern markets and had purchased an additional acreage for this purpose. It had been a wet spring delaying the progress on the clearing, tilling and planting the new acreage. Now WOGC was under a tight deadline to get the brush cleared, tilled and Blue Wave planted.
Identify the leadership style for Paul and Jared? Who should George put in charge of the project? Why?

Scenario:
Midal cables limited, is currently considering the launch of a new product. A market survey was recently commissioned to assess the likely demand for the product and this showed that the product has an expected life of four years. The survey cost $30,000 and this is due for payment in four months’ time. On the basis of the survey information as well as internal management accounting information relating to costs, the assistant accountant prepared the following profit forecasts for the product.

These profit forecasts were viewed with disappointment by the directors and there was a general feeling that the new product should not be launched. The Chief Executive pointed out that the product achieved profits in only two years of its four-year life and that over the four-year period as a whole, a net loss was expected. However, before a meeting that had been arranged to decide formally the future of the product, the following additional information became available:
The new product will require the use of an existing machine. This has a written down value of$80,000 but could be sold for $70,000 immediately if the new product is not launched. If the product is launched, it will be sold at the end of the four-year period for $10,000.
Additional working capital of $20,000 will be required immediately and will be needed over the four-year period. It will be released at the end of the period.
The fixed overheads include a figure of $15,000 per year for depreciation of the machine and $5,000 per year for the re-allocation of existing overheads of the business.
The company has a cost of capital of 10%.
Ignore taxation.
Required
Use integrated financial software you are familiar with and perform the task below. For example, you may use excel spreadsheet for calculation and presentation of cash flow and Microsoft word to explain the phenomenon.
Calculate the incremental cash flows arising from a decision to launch the product.
Calculate the approximate internal rate of return of the product.
Explain, with reasons, whether or not the product should be launched. (50-100 words)

Java. Given an input file with each line representing a record of data and the first token (word) being the key that the file is sorted on, we want to load it and output the line number and record for any duplicate keys we encounter. Remember we are assuming the file is sorted by the key and we want to output to the screen the records (and line numbers) with duplicate keys. We are given a text file and have to use the scanner class to lod it
Your task is to
create a FindDuplicates class with the following:
Declaration of an instance variables for the String filename
non-default Constructor - creates an object for user passed filename argument
Accessor methods return the value of each instance variable
Mutator methods that allows th user to set each instance variable (no validation required),
a "getDuplicates()" method that reads from the file (until end-of-file) using Scanner class, finds duplicate records based on the first token on each line (the key), and returns as a String the record number and entire duplicate record one to a line (see above Sample output)
toString() - returns a String message with the value of the instance variable
Sample Output
Enter File Name: input1.txt
FileName:input1.txt
