C++

 

This is a written assignment where you will research answers to the below questions. All answers will be in your own words. Any copy/paste = 0/100. Feel free to use a combination of text and code if that helps you explain a concept easier. 

Please type your answers to the below questions in a Word document, 12 pt font, single space (please put a blank line between each answer to separate them):

  1. What is object-oriented programming (OOP)? Give examples
  2. Name at least two benefits of OOP. Give examples
  3. What is an object? Give an example
  4. What is a class? Give an example
  5. There are main components of OOP, define each and also explain how works with examples:
    1. Inheritance
    2. Polymorphism
    3. Encapsulation
    4. Data abstraction

I expect to see detailed answers to each of the above. Short, vague answers will result in a low grade. 

THE FUTURE OF LIFE INSTITUTE

 Elon-Musk donated $10 million to a foundation called the Future of Life Institute.  The institute published an open letter from an impressive array of AI experts who call for careful research into how humanity can reap the benefits of AI “while avoiding its pitfalls.”  Go online and find out about the institute’s initiatives.  What are its primary goals?  How can humans establish and maintain careful oversight of the work carried out by robots?  How valid are Elon Musk, Bill Gates, and Stephen Hawking’s concerns?  What other concerns should the public bear in mind as the technological revolution advances? 

Parametric and Non Parametric Analyses

 

Part 1

A principal wants to determine if a new ACT preparation program is effective. The data are contained in the schools.sav data file. Open the schools.sav file in SPSS. Use SPSS to determine whether a significant improvement existed between student performance on ACT tests in 1993 (act93) and ACT tests in 1994 (act94). Assume that the same students were involved in 1993 and 1994 testing. (This requires a t-test. Review Chapter 10 of the Green & Salkind text for information on paired t-tests and reporting APA results interpretation and writing.)

Create a report that answers the principal’s question. Write these conclusions in formal APA results format. Include your SPSS output to support your conclusion.

Part 2

A pharmaceutical company wants to determine whether there is a need for a new medication based on the data in the electric.sav file. Specifically, they want to determine whether a person is alive or dead 10 years after a coronary incident and whether that is reflected in a significant difference in the patients’ cholesterol levels (chol58) taken when the event occurred. Use chol58 as a dependent variable and VITAL10 as your independent variable. Complete the following:

  • Analyze these conditions to determine whether there is a significant difference between the cholesterol levels (vital10) of those who are alive 10 years later compared to those who died within 10 years.
  • Include the SPSS output, which validates your conclusion.
  • Write a brief paragraph describing your conclusions.

Refer to Unit 6 in the Green & Salkind text for specific information about SPSS tests and APA results interpretation and writing. Pay attention to the Levene’s test throughout for determining whether the assumption of equal variance was met when you make your final decisions about the analysis.

What conclusion did you reach? Write these conclusions in formal APA results format. Include your SPSS output to support that conclusion.

Part 3

Occasionally, you have 1 independent variable that has 3 or more levels or groups. For a parametric data set, an analysis of variance (ANOVA) is the proper calculation. Use an ANOVA to address the following scenario:

A financial planner is interested in understanding the relationship between the dependent variable of the income level of respondents (rincdol) and the independent variable of their education level (ndegree) from the gss.sav data file. Use SPSS to complete the following:

  • Run an ANOVA to determine the overall conclusion.
  • Use the Bonferroni correction as a post-hoc analysis to determine the relationship of specific levels of degree level to income.
  • Explain the overall conclusions based on the analysis, and describe the relationship(s) between the levels of the degree earned and income.
  • Write your conclusion of the findings based upon the output using proper APA formatting.

Submit both the SPSS output file and your Word summary. (Refer to the Green & Salkind section about a one-way ANOVA for information on APA results interpretation and writing.)

Security Architecture and Design

 

Briefly respond to all the following questions. Make sure to explain and backup your responses with facts and examples. This assignment should be in APA format and have to include at least two references and 600 words.

As you consider the reputation service and the needs of customers or individual consumers, as well as, perhaps, large organizations that are security conscious like our fictitious enterprise, Digital Diskus, what will be the expectations and requirements of the customers? Will consumers’ needs be different from those of enterprises? Who owns the data that is being served from the reputation service? In addition, what kinds of protections might a customer expect from other customers when accessing reputations?

Discussion Post-cloud

 

Discuss  500 words or more discuss why Security as a Service is a good investment.

Cite your sources. Do not copy. Write in essay format not in bulleted, numbered or other list format. 

Tableau- Wine Quality

Before You Begin

  • This assignment will be saved to your Tableau Public account rather than GitHub.
  • If you haven’t already, be sure to create a Tableau Public account here.
  • The free tier of Tableau only lets you save to their public server. This means that each time you save your file it will be uploaded to your Tableau Public profile.
  • You are able to load and continue working on the same workbook.
  • When you are finished with your assignment, you will turn in the URL to your Tableau Public workbook along with any additional files used for your analysis.

Background 

Picture…hosting a nice holiday party for close friends… having prepared all of the expected holiday hors d’oeuvres and the most beautiful charcuterie board in the world.. holiday music playing in the background. But wait….how could you possibly make this party any better…… WINE.

 The importance of selecting a wine to pair with food makes or breaks the flavor combination. With so many options for different types of white and red wines, we are giving you an inside look at the quality of wine and what truly contributes to choosing the better quality. We will be analyzing different traits in both white and red wine such as alcohol content, sugar levels, acidity, color, etc. to gain a better understanding on how each contributes to the quality. 

Task

Your task in this assignment is to aggregate the data found in the Wine Quality dataset from Kaggle. 

Analyzing different traits in both white and red wine such as alcohol content, sugar levels, acidity, color, etc. to gain a better understanding on how each contributes to the quality. 

Design 2-5 visualizations for each discovered phenomena (4-10 total).  

Next, as a chronic over-achiever:

  • Use your visualizations (does not have to be all of them) to design a dashboard for each phenomena.
  • The dashboard should be accompanied with an analysis explaining why the phenomena may be occuring.

 A link to your Tableau Public workbook that includes:

  • 4-10 Total “Phenomenon” Visualizations
  • A Dashboard
  • A text write up :  analysis on the phenomenons you uncovered from the data

 

Sharing Your Work

In order to share your work, we are asking that you will save your workbook as a .twbx file so that your TA’s can grade them.

To save your workbook as a .twbx file, you will just need to select “Save As…” from the “File” dropdown. Then, select the .twbx option.
