• Assignment Topic: MS Office Integration.
  • To make this assignment as simple as possible, all you must do is to write about the use of the computer applications we are studying this month in real world settings. (excel, powerpoint, word) For instance, you can write about how you use or plan to use them at home or work place, or about somebody that you know or a business that use these applications. (Please be sure you write around this topic, if you write about something not related to this topic and class you will receive a ‘0’; I am required to enforce this).
  • You can read Chapter 22 in your textbook (Integrating Word, Excel, Access and PowerPoint) to learn more about this subject and have a better idea about what to look for in your research and write.
• General Guidelines:
  • You must use APA writing style guidelines to write your paper.
  • After conducting your research, write to present your findings and in a very simple way or tell how these applications affect your work, position, and/or field of expertise to make you more productive in the office activities you are or will be performing soon or even here at Everglades University while attending your classes.
  • In this class ONLY, I want you to keep your research very simple/basic.
  • I need you to focus on the APA writing style format of your assignment and learning the correct use of MS Word controls and features to write a paper that conforms with APA writing style guidelines format, this way you will be ready for the rest of your classes and will be using MS Word the correct way for that.
• Requirements:
  • Assignment MUST be submitted as a Word document. (.docx or .doc)
  • Contains at least four pages:
    • Page one: Title (AKA for many students as Cover Page).
    • Page two: Abstract (Remember NOT to indent the abstract section).
    • Page three: Body (At least two short paragraphs of any length that will allow you to insert the required in-text citations).
    • Last Page: References (At least 3 different that must come from the source list you created in the Insert Citation Source list).
  • Font type: Times New Roman.
  • Font size:
    • 14 points for running headers only.
    • 12 points for headings and everything else in your document.
  • Font color: Black.
  • Alignment: Left align.
  • Line Spacing: Double space.
  • Paragraph Spacing: None after each paragraph.
  • Quote from the article(s) when appropriate and use at least three proper Word generated in-text citations in the paper’s Body conforming to APA writing style guidelines.
  • References must be MS Word generated from using the source list created to insert the required citations.
  • Must include “Running head and a colon” text before the actual header on Title Page ONLY, the rest of pages must use the header alone, left aligned.
  • Must include page numbers in all pages, right aligned and MUST be in the same line as the running header.
  • No spelling and grammar mistakes.
  • Paper Body must use a header (Notice that this may already have been covered by the Running Header since this exercise is a single topic paper).
  • Please, DO NOT convert citations or references to static text, the placeholders need to be active to be reviewed, thank you!

This assignment is due on Sunday of the third week of class, September 20th.

Final Exam DPEE

Note: 

· For demonstrating conceptual understanding, you are required to work on the model that is easier to handle or compute, not necessarily the more suitable (or more complicated) model for the dataset. Follow the question description. 

· You don’t need to check the assumption of a model unless the question asks for it. For example, if the question asks you to make prediction based on a model, you don’t need to check the assumption for the model before making prediction. 

· For any of the testing (hypothesis test) problem, define Ho/Ha, compute the test statistic, report the exact p value, and state the conclusion. The default alpha value is 5%, unless specify. 

· Elaborate your reasoning clearly and show relevant plots, R results, and tables to support your opinion in each step and conclusion. 

· Submit the Rmd file and the corresponding pdf file knitted from it, along with your answer, this format is similar to your homework. 

· The data is real, just like the project you are working on. Hence it is possible that even after the remedial method has been done, the model is still not perfect. When this happens, evaluation will be based on the level you execute the methods covered in Stat512 to improve the model. Don’t worry if your model is not perfect, try your best to demonstrate the skill set you learn in this class. 

Study the data with a linear analysis and complete the problems. The data set, dataDPEE.csv has 3 continues predictors and two categorical predictors. 

Problem 1. Consider only the first order model with X1, X2 and X3, perform the following hypothesis. 

a. (10) whether X1 can be dropped from the full model. 

> dpeemod <- lm(y ~ x1 + x2 + x3)

> plot(dpee)

> summary(dpeemod)

Call:

lm(formula = y ~ x1 + x2 + x3)

Ho: X1 is significant and cannot be dropped from the model.

Ha: X1 can be dropped from the model. 

Using the model Y~X1 + X2 + X3, 

b. (10) whether X1 can be dropped from the model containing only X1 and X2. 

Problem 2 (10) Consider the first order model with X1, X2 and X3, simultaneously estimate parameters (beta1, beta2 and beta3)  with a confidence level of 75%. 

Problem 3 (20) Perform appropriate analysis to diagnose the potential issues with the first order full mode with X1 X2 and X3, improve the model as much as possible with the methods covered in Stat512. You should also consider the assumption checking for your revised model.  

Problem 4 

a. (10) Compute AIC, BIC, and PRESSP to compare the following two models. 

· The model on the first order terms for X1 and X2 and the interaction term X1X2.

· The model on the first order terms for X1, X2 and X3 

Do they all yield the same better model? If not, explain. 

b. (10) Select the model that you think is better to predict the mean response value, then predict the mean response for the following case, at a confident level of 99%.

Problem 5 

X4 and X5 are two factors on Y.

a. (10) Is there any significant interaction effect between X4 and X5 on Y? 

b. (10) With the ANOVA method, compute the 95% confidence interval for the following difference, respectively: 

D1= The difference in the mean of Y when (X4=high, X5=less) and (X4=high, X5=more) 

D2= The difference in the mean of Y when (X4=low, X5=less) and (X4=low, X5=more) 

c. (10) With the ANOVA method, compute the 95% confidence interval for 

D1-D2

Where D1 and D2 are described in b. 

How is your result related to a? 

While this weeks topic highlighted the uncertainty of Big Data, the author identified the following as areas for future research.  Pick one of the following for your Research paper:

• Additional study must be performed on the interactions between each big data characteristic, as they do not exist separately but naturally interact in the real world.
• The scalability and efficacy of existing analytics techniques being applied to big data must be empirically examined.
• New techniques and algorithms must be developed in ML and NLP to handle the real-time needs for decisions made based on enormous amounts of data.
• More work is necessary on how to efficiently model uncertainty in ML and NLP, as well as how to represent uncertainty resulting from big data analytics.
• Since the CI algorithms are able to find an approximate solution within a reasonable time, they have been used to tackle ML problems and uncertainty challenges in data analytics and process in recent years.

Your paper should meet these requirements: 

• Be approximately four to six pages in length, not including the required cover page and reference page.
• Follow APA 7 guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.
• Support your answers with the readings from the course and at least two scholarly journal articles to support your positions, claims, and observations, in addition to your textbook. The UC Library is a great place to find resources.
• Be clearly and well-written, concise, and logical, using excellent grammar and style techniques. You are being graded in part on the quality of your writing.

A Command-Line Interpreter, or Shell

Your shell should read the line from standard input (i.e., interactive mode) or a file (i.e., batch mode), parse the line with command and arguments, execute the command with arguments, and then prompt for more input (i.e., the shell prompt) when it has finished. This is what Minor 2 program should do with addition of batch processing which means just reading a batch line by line and calling the same interpretation logic.

1. Batch Mode

In batch mode, your shell is started by specifying a batch file on its command line. The batch file contains the list of commands that should be executed. In batch mode, you should not display a prompt, but you should echo each line you read from the batch file back to the user before executing it. After a batch is finished the shell will exit.

1. Interactive Mode

No parameters specified on command line when the shell is started. In this mode, you will display a prompt (any string of your choice) and the user of the shell will type in a command at the prompt.

You will need to use the fork() and exec() family of system calls. You may not use the system() system call as it simply invokes the system’s /bin/bash shell to do all of the work. You may assume that arguments are separated by whitespace. You do not have to deal with special characters such as ‘, “, , etc. You may assume that the command-line a user types is no longer than 512 bytes (including the ‘n’), but you should not assume that there is any restriction on the number of arguments to a given command.

a) Select a problem that a firm might have bringing out a new product or service and discuss how the firm could overcome that problem 350 words and in APA formate 

b) 1 reply of 250 words

Managing Risk

Your company has decided to implement a human resource demographic portal.  Under the system envisioned, employees would be able to use an online internal web page to change various personal information items themselves, such as, address phone, etc.  In addition, the employees would be able to change limited payroll related items, such as 401k deduction percentages or amounts, optional United Way contributions, and the number of federal and state exemptions to be claimed. Along with thie portal would be the ability to view, download, and print current and YTD pay information, including the current paycheck and check “stub”.  

Under the current system, employees must go to the HR office to make any changes – there is no online access.

Your company already requires direct deposit for all employees, and under the new system, pay stubs would no longer be printed.  Employees would be able to do this as needed through the portal.

 There are many potential risks associated with this project. 

1. Your task is to Identify as many risks as you can (4 is a minimum, but feel free to identify more risks if you so desire).
2. Determine the relative likelihood of each risk occurring (low, medium high)
3. Propose at least one strategy for addressing each risk, and describe the strategy in terms of the 4 risk responses (Avoidance, Transference, Mitigation, or Acceptance).

Remember that sometimes, risks are acceptable and can be taken, so long they are identified and a strategy to address the risk is presented.  For example, driving a car is a risky venture, but to address that risk we have driver’s education (mitigation), manufacturing safety standards (mitigation), insurance (transference), and staying at home (avoidance). Driving an older, unsafe vehicle by an unlicensed and uninsured motorist could be considered acceptance,

.

Turn in as much as needed. (Sometimes less is more, sometimes more is more; it’s your call.)

Support your strategies as needed with external references, and make sure your answer directly address the potential risks with the  human resource demographic portal.
