Note: using Visio Microsoft to draw ER Diagram – ERD
Use the NFL report to identify entities and to create an ERD complete with foreign/primary keys and minimum and maximum cardinalities. (50 Points)
You need to create the logic for a database for the IT department for University to track the computers used within the classrooms. Computers are spread throughout campus in each building, and there are some rooms with a single computer and some labs with multiple computers. Creating an ERD, and then you should describe each computer as well as identify the room and further describe the desk/location of the computer. You should examine the characteristics of the lab and the computers there to determine how the information may be recorded. The relationships must have cardinalities, and you should list the primary and foreign Keys. You should list any assumptions that are made for the relationships.

Progress CheckUse this activity to assess whether you and your peers can:
Use a two-way table to examine the relationship between two categorical variables.
ContextHere is a review of the information from the previous page.
We randomly selected 1,200 participants from the 2020 Race IAT. Below is the two-way table for the sample with the row variable Race and the column variable Crime-Focus. Here is a description of each variable.
Race: IAT participants’ self-reported race.
Crime-Focus: IAT participants’ response to the statement, “Law enforcement officers should pay particular attention to those social groups more heavily involved in crime, even if this means focusing on members of particular ethnic groups.”

Be sure to number your responses, show your work, and write your answers in context as we did on the previous page.
Are black IAT participants more likely than whites to strongly agree that law enforcement officers should focus their attention on particular social groups?
Are white IAT participants more likely than multiracial participants to moderately or strongly agree that law enforcement officers should focus their attention on particular social groups?

This criterion is linked to a Learning OutcomePeer Review
2 ptsFull Credit
You completed the assigned peer review. The points you assigned in the rubric for the “Addressing the Prompt” criterion are appropriate. You used the “Add a Comment:” field to submit your assignment comments. Your assignment comments relate the score you assigned in the “Addressing the Prompt” criterion of the rubric to how your peer addressed the learning objectives when responding to the “Prompt.” (Note: the learning objectives are listed in the “Progress Check” section of the assignment.) If you awarded full credit for the “Addressing the Prompt” criterion in the rubric, your comments contextually and specifically explain what your peer did to demonstrate attainment of the relevant learning objectives. If you deducted points for the “Addressing the Prompt” criterion, you clearly explained what your peer can do better to demonstrate attainment of the relevant learning objectives.
1 ptsPartial Credit
You committed a good-faith effort to provide a high-quality peer review, but necessary instructive comments are missing. Or, you provided appropriate instructive comments but did not complete the rubric.

Total Points: 10

I need numbers and an explanation for the excel example I am providing let it contain the total score based on the sum of all 36 items, which can range from ILS requires 12, so delete one set of the 13 so put the data for 1 of the item into the WEIM to make it 18 instead of 17 so the dataset could be complete. I need to know an explanation of what they represent, and I need to have the complete data set. Please do an answer in word and fix the excel sheet. I am sending a draft of the paper for you to match the graphs and figures the excel to fix and explain thanks I don’t have the datasheet you pretty much have to just fix it up according to to match the appropriate dataset my professor said you could leave to 1-5 that’s alright. Do you have any information to match up for JSS calculation datasets?
These are figures that I need for Job Satisfaction – The Job Satisfaction Scale (JSS) has 36 items that are scored on a 6-point scale of 1 to 6, with 9 subscales (4 items each). I have attached an article on the JSS that you may want to review. I also found an article on a different JSS version that has 20 items scored using a 5-point Likert scale ranging from 1-5

To assess your ability to:

Grading Criteria
Thorough responses and active enagegment on dsicussion board: 0 – 7 points

Complete the case problem, “Forecasting Food and Beverage Sales” located at the end of chapter 17 in Modern Business Statistics 7e . Upload your report and discuss your findings and recommendations.
Note : make sure to include outside sources to support your discussion.

You have found a large set of historical data, and are working to analyze and find patterns in the data set. The coach of the team and your management have requested that you perform several hypothesis tests to find the statistical significance of the claims that are being made about your team. This analysis will provide evidence to validate critical claims and get statistically valid findings that will help make key decisions to make the team better in upcoming seasons. You will use the Python programming language to perform statistical analysis and will also need to present a report of your findings to the team’s management. Since the managers are not data analysts, you will need to interpret your findings and describe their practical implications. The managers will use your report to find areas where the team can improve its performance.
Note: This data set has been “cleaned” for the purposes of this assignment.

I completed the assignment only to realize that it was not correct because I needed a different type of article. May I have some help with this article critique?
The practice of quantitative research not only involves statistical calculations and formulas but also involves the understanding of statistical techniques related to real-world applications. You might not become a quantitative researcher nor use statistical methods in your profession but as a consumer, citizen, and scholar-practitioner, it will be important for you to become a critical consumer of research, which will empower you to read, interpret, and evaluate the strength of claims made in scholarly material and daily news.
For this Assignment, you will critically evaluate a scholarly article related to logistic regression.
To prepare
Review the Article Critique Assignment Guide in the Walden Library, listed in the Week 2 Learning Resources.
Search the Walden Library for a quantitative article that applies binary logistic regression.
By Day 7
The Assignment
Write a 2- to 3-page critique of the research you found in the Walden Library that includes responses to the following prompts:
Why did the authors select binary logistic regression in the research?
Do you think this test was the most appropriate choice? Why or why not?
Did the authors display the results in a figure or table?
Does the results table stand alone? In other words, are you able to interpret the study from it? Why or why not?

This involves the use of Stata
The answer must be one page per question, with font size 12 and double spaced.
a template answer sheet is provided for you to follow. Please note that most questions require short and concise answers.
Other questions can be answered with a self-contained table (we will cover this on week 6 in the lab, please refer to the guidelines on tables in the STATA guide). Please number your tables with the question number (i.e. “Table 1.2.” reports the results for question 1.2. in the text as well as in the do-file.)
You also need to provide an Appendix that contains a STATA log file (resulting of running a do file) that shows how you have solved each question.
Please show your calculations in the main text of the project (even if they are done in the do file).
You must use the template answer sheet and the template appendix given at the end of the document, and please follow all the instructions. Please fulfil all the questions and all the questions.
Word requirements: 5 pages of word document, with font size 12 and double spaced, one subquestion eg 1.1 for one page.
