the aim of this first assignment is to implement a Linked List that is able to hold and operate on more complex data (than just one number, string, etc.). 

Specifically, the task is to create a set of flash cards. The “deck” of flash cards can be thought of as a linked list. Each flash card should have a hint (e.g. “an ADT that typically has push and pop operations”), and then will prompt for an answer from the user. The program should go through the deck of flash cards (i.e. traverse the linked list). 

See the video here for a short demonstration of what the program should look like when it is run:

What to hand in?

A single *.py file should be submitted here on Canvas. Do *not* put your name anywhere in the *.py file since this will be anonymously reviewed. 

The example of how the ouput should is the first screen shot i’ve added. the next 2 screen shots are how the assignment is graded.

Additional requirements/specs:

• the program should have at least 3 flash cards
• you should choose hints and answers other than those that are shown in the demonstration video
• your cards (the hints and answers) should be hard-coded inside of your program (you do not want to have to input the cards in your program each time it is run, and, when someone else runs your program they will be able to see new flash cards that they have not seen before)

Hints/Tips:

The flow of the program is that we iterate through the deck of flash cards (i.e. the linked list), and remove a card (i.e. node) when it has been answered correctly twice. Thus, iterating over the linked list, keeping track of correct answers, and stopping when the list is empty, is 90% of the task here. Try to push as much functionality into your flash cards (nodes), and deck (list) as possible. That way the main part of your program can be very short and simple. 

The python function, “input()” will be helpful. Here is how it could be used in this program:

answer = input("ENTER 'S' FOR STACK, 'Q' FOR QUEUE', OR 'L' FOR LIST")

Specifically the following critical elements must be addressed:

1. Analyze a recent news headline of a retail chain that has been breached recently.
2. Assess the cause of the retail chain breach.
3. Determine steps that can be taken moving forward to resolve the breach.

Guidelines for Submission: Your paper must be submitted as a two- to three-page Word document with double spacing, 12-point Times New Roman font, one-inch margins, and at least two sources cited in APA format

Three Required Headers:

Resolution

The majority of online fraud occurs through electronic communication. We receive emails daily that represent some type of phishing scheme or web spoofing, which can be deleted with a simple click of the delete button. But what happens when your personal information has been stolen through a third-party vendor’s technical error while you made a purchase from your local retail store, who stores your credit card and personal information within a remote database?

Research a recent news headline of a retail chain that has been breached recently and analyze the scenario. What caused the issue? What steps can be taken moving forward to resolve the issue? Use research and specific examples to support your resolution recommendations.  

1 page in APA 6th Format On human resource management NO PLAGIARISM

Reflect on a few key concepts with at least one scholarly (peer-reviewed) resource :

1. Discuss the key components of human resource management.  Pick at least four concepts from chapter nine and describe how these concepts interrelate to individual performance on a team.
2. Review table 9.2 and select one of the dimensions listed, note why it was chosen and how you relate to this behavior.  If you have a personal experience, please share.
3. How do leaders select the best talent? What are some tools they can use to select the best-talent?

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.

> plot(dpee)

> summary(dpeemod)

Call:

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.

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)

How is your result related to a? 

Your task is to develop a proof of concept by building a virtual  machine on the AWS cloud platform to host the company’s current  infrastructure. For the purpose of the lab, you will use Amazon Virtual  Private Cloud (VPC) to create your own VPC and launch a web server to  host the company’s web server. You will also create security groups for  an EC2 instance, configure and customize the EC2 instance to run the web  server, and launch it into the VPC. 

For this project, you will need to complete the “Build a Virtual  Private Cloud and Launch a Web Server” hands-on activity and include  screenshots of your work in the project. Read the report template before  starting the activity for instructions on required screenshots.

Use the Proof-of-Concept Report Template to  prepare a report that shows the steps and results for the proof of  concept. In the template, you will see specific instructions in the  document. Delete the instruction text before you submit your project.

Your report should:

• Be five to seven pages long (plus an appendix for screenshots, cover page, and table of contents) 
   
• Address the topics listed in the Proof-of-Concept Report Template
   
• Include the following screenshots from the “Build a Virtual Private Cloud and Launch a Web Server” activity:
   
  • Start Lab page 
     
  • AWS Management Console Name with your name visible from user drop-down 
     
  • Task 1: Create Your VPC
     
  • Task 2: Create Additional Subnets
     
  • Task 3: Create a VPC Security Group
     
  • Task 4: Launch a Web Server Instance
