Assignment Content

1. Imagine this scenario: Pine Valley Furniture’s board of directors is ready to review how to implement and maintain the new WebStore system. 

   Create a 6- to 8-page APA formatted implementation and maintenance plan in Microsoft® Word® for the new WebStore in which you:

   • Recommend an installation strategy (referring to Chapter 13 of “Structuring System Process Requirements” from Modern Systems Analysis and Design) (i.e., direct, parallel, single-location, or phased installation) for Pine Valley Furniture’s student furniture WebStore.
   • Justify your recommendation by stating the advantages and disadvantages in comparison to the 3 other installation strategies and describe why your recommendation would be the best for Pine Valley Furniture’s student furniture WebStore.
   • Summarize the information needed for the documentation that you would suggest creating for the Pine Valley Furniture WebsStore project to:
   • Document the system
   • Train and support users
   • Summarize the information needed for the Pine Valley Furniture project’s system testing plan.
   • Briefly describe the activities needed for the Pine Valley Furniture WebsStore project’s testing plan elements.
   • Summarize Pine Valley Furniture WebsStore WebStore’s maintenance needs, including:
   • Alternate organizational structures
   • Quality measurement
   • Processes for handling change requests
   • Configuration management
   • Please make sure your material is specific for the Pine Valley Furniture project and not just generic material

     Provide any references and citations according to APA guidelines. Please review the Center for Writing Excellence material regarding references, citations, paraphrasing, plagiarism and the Student Code of Academic Integrity. To sum this up, proper references and citations are needed for all of your work – just having a list of References at the end is not sufficient.

     Please note that this assignment is graded according to a standard rubric. Please review the grading rubric to begin organizing your assignment. It clearly defines expectations and is what your faculty member will use to grade your submission.

     Submit your assignment.

     Please note that I do not consider simply parroting back material from another source to be sufficient – you will need to provide your material in your own words and discuss or describe how any external material you provide relates to the scenario. Also, please make sure you properly paraphrase, quote, reference and cite any material you are discussing.

Week 5 – Research Paper Bitcoin Economics

This week’s reading centered around Bitcoin Economics.  For this week’s research paper, search the Internet and explain why some organizations are accepting and other organizations are rejecting the use of Bitcoins as a standard form of currency.  Your paper needs to identify two major companies that have adopted Bitcoin technology as well as one that has refused accepting Bitcoin as a form of currency. Be sure to discuss each organization, how they adopted (or why they won’t adopt) Bitcoin, and what recommendations you have for them to continue to support Bitcoin (or why they should support Bitcoin).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.

 Explain Project Management and identify the primary reasons projects fail.

For your final assessment, you will use your work from the previous four assessments, along with this final piece to produce a cohesive plan for enterprise network optimization. Organize your work logically, as if you would actually present it to senior IT leadership in the organization you selected.

Use the following structure to organize and complete your assessment:

• Title page.
• Executive summary (approximately one page that provides a high-level overview of what is in the document).
• Body of the document:
  • Your network diagram, updated to include the following:
    • Apply basic load-balancing techniques as an effort to ensure network availability.
  • Analyze the technology presented in your diagram (you may use the information you provided in previous assessments, but do not simply cut and paste).
    • Explain your decisions for hardware placement, hardware devices, topology, and overall infrastructure design.
    • Support your analysis with recent, relevant resources.
  • Explain the techniques and strategies for maintaining high availability on the network.
  • Explain your load balancing strategy.
  • Explain how your network design addresses globalization. How can you be sure it will succeed internationally?
• References page.
  • Include at least six recent, relevant professional references.
  • Format references according to APA guidelines.

Additional Requirements

• Use the following template: Assessment 5 format.docx 
• 6–8 double-spaced pages, not including the title page and references page.
• Be sure it is professionally written
• free of errors
• Times New Roman, 12-point font.

Grading

Ensure you are following the scoring guide; this is how I will grade your paper:

• Design a network for an organization.
• Analyze the technology presented in a network design diagram.
• Explain the techniques and strategies for maintaining high availability on the network.
• Explain the load balancing strategy.        
• Explain how a network design addresses globalization.
• Write clearly with few spelling, grammatical, or mechanical errors.

An ANOVA is when we want to run a means test on more than 2 groups. However, the same basic structure of the hypothesis testing that we have done remains.

Using the hockey data, test if there is a difference between the true average number of goals scored by the different divisions. Second, test if there is a difference between the actual mean number of goals allowed by teams of different quality (where teams with at least 100 points is the top tier, those with 90-99 are the middle tier, and those with less than 90 make up the bottom tier).

If either of these tests show significance, run a multiple comparisons test among the groups. (Note that this is essentially the two sample testing we just did but with an adjustment to ensure that we don’t have inflated error probabilities.) Use a 0.05 significance level for all tests.

As you do this for your own data set, ensure that at least one of the two problems shows significance and requires pairwise comparisons. Unless impossible to avoid, do not use more than 4 groups — there’s nothing that says you can’t, but it’ll make your report much more tedious. Also note that if you only have 2 groups, that’s a two sample independent mean test and not an ANOVA; we did that last assignment, so ensure that you have at least 3 groups in your analysis.

Deliverable:
– A word document answering the following questions
Using the Weather.csv dataset from Module 4
Part 1: Metrics for Evaluation
1. Calculate the following metrics: mean absolute error, mean squared error, root mean
squared error, and the R2 score. Use the following code samples:
print(‘Mean Absolute Error:’, metrics.mean_absolute_error(y_test,
y_pred))  
print(‘Mean Squared Error:’, metrics.mean_squared_error(y_test,
y_pred))  
print(‘Root Mean Squared Error:’,
np.sqrt(metrics.mean_squared_error(y_test, y_pred)))
print(‘R-squared Score:’, regressor.score(X, y))
Part 2: Model Refinement
1. Rerun the linear regression model from Module 4, but change the percentage of records
that are used for testing. Try using 0.25 and 0.3.
2. Calculate the same metrics from above.
3. Use a scatter plot to visualize all three models.
4. Evaluate the three models. Are any of them underfit or overfit? Which % of testing data
performed best?
