The purpose of this assignment is to apply simple regression concepts, interpret simple regression analysis models, and justify business predictions based upon the analysis. For this assignment, you will use the "Trucks" dataset. You will use SPSS to analyze the dataset and address the questions presented. Findings should be presented in a Word document along with the SPSS outputs. The business characteristics of n = 250 U.S. trucking and delivery companies for calendar year 2011 were recorded. Among the characteristics studied were the number of drivers and the number of trucks (power units) each company employed. Part 1: Given that the data consists of counts and range of counts is large, a natural log transformation is usually performed to improve the linear model results. Apply a natural log transform to both variables and then plot the Y = log(Trucks) vs. X = log(Drivers). Is there a linear relationship? Justify your answer by providing the SPSS output as an illustration. Part 2: Build a simple linear model by regressing Y on X and testing whether or not a relationship exists between the number of drivers and the number of trucks. Address the following questions in your written response: After fitting the model, plot the standardized residuals (on vertical axis) vs. the standardize predictions (on horizontal axis). Is there a pattern? How would you interpret the pattern or lack of pattern? After fitting the model, derive the normal probability plot and interpret what the plot means. What is the coefficient of determination, R2, of the model? How would you interpret the R2? What is the estimate of β1? How would you interpret the estimate of β1? Is the estimate of β1 significantly different than 0? Assume an α = 0.01. What is a 95% confidence interval for β1? How would you interpret the 95% confidence interval for β1? If a new trucking and delivery company with 4,900 drivers were to be formed, how many trucks would you expect the company would employ based on the model? This assignment uses a grading rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion. 1 Unsatisfactory 0.00% 2 Less than Satisfactory 74.00% 3 Satisfactory 79.00% 4 Good 87.00% 5 Excellent 100.00% 100.0 %Content 15.0 %Simple Regression Analysis Part 1 Discussion of the linear relationship and supporting SPSS output chart are not included.

Answers to simple regression analysis questions and supporting SPSS output charts are incomplete or incorrect. Answers to simple regression analysis questions and supporting SPSS output charts are included but contain errors or inaccuracies. Answers to simple regression analysis questions and supporting SPSS output charts are mostly complete and accurate. Answers to simple regression analysis questions and supporting SPSS output charts are complete and accurate. 10.0 %Mechanics of Writing (includes spelling, punctuation, grammar, language use) Surface errors are pervasive enough that they impede communication of meaning. Inappropriate word choice or sentence construction is used. Frequent and repetitive mechanical errors distract the reader. Inconsistencies in language choice (register) or word choice are present. Some mechanical errors or typos are present, but they are not overly distracting to the reader. Correct and varied sentence structure and audience-appropriate language are employed. Prose is largely free of mechanical errors, although a few may be present. The writer uses a variety of effective sentence structures and figures of speech. Writer is clearly in command of standard, written, academic English. 100 %Total Weightage

PROJECT DELIVERABLE 3: DATABASE AND DATA WAREHOUSING DESIGNThis assignment consists of two (2) sections: a design document and a revised project plan. You must submit both sections as separate files for the completion of this assignment. Label each file name according to the section of the assignment it is written for. Additionally, you may create and / or assume all necessary assumptions needed for the completion of this assignment.One of the main functions of any business is to transform data into information. The use of relational databases and data warehousing has gained recognition as a standard for organizations. A quality database design makes the flow of data seamless. The database schema is the foundation of the relational database. The schema defines the tables, fields, relationships, views, indexes, and other elements. The schema should be created by envisioning the business, processes, and workflow of the company. Since your company is an innovative Internet-based company, movement toward data warehousing seems to be one of the most viable options to give your company a competitive advantage; however, these concepts must be explained to the executive board in a manner to garner support.Section 1: Design DocumentWrite a six to ten (6-10) page design document in which you:Support the need for the use of relational databases and data warehousing. From a management standpoint, it may be important to show the efficiencies that can be gained for executive oversight.Create a database schema that supports the company’s business and processes. Explain and support the database schema with relevant arguments that support the rationale for the structure. Note: The minimum requirement for the schema should entail the tables, fields, relationships, views, and indexes.Identify and create database tables with appropriate field-naming conventions. Then, identify primary keys and foreign keys, and explain how referential integrity will be achieved. Normalize the database tables to third normal form (3NF).Identify and create an Entity-Relationship (E-R) Diagram relating the tables of the database schema through the use of graphical tools in Microsoft Visio. Note: The graphically depicted solution is not included in the required page length but must be included in the design document appendix. Explain your rationale behind the design of the E-R Diagram.Identify and create a Data Flow Diagram (DFD) relating the tables of your database schema through the use of graphical tools in Microsoft Visio or an open source alternative such as Dia. Note: The graphically depicted solution is not included in the required page length but must be included in the design document appendix. Explain the rationale behind the design of your DFD.Illustrate the flow of data including both inputs and outputs for the use of a data warehouse. The diagram should map data between source systems, operational systems, data warehouses and specified data marts. Note: The graphically depicted solution is not included in the required page length.Your assignment must follow these formatting requirements:Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.Include charts or diagrams created in MS Visio or Dia as an appendix of the design document. All references to these diagrams must be included in the body of the design document.Section 2: Revised Project PlanUse Microsoft Project to:Update the project plan (summary and detail) template, from Project Deliverable 2: Business Requirements, with three to five (3-5) new project tasks each consisting of five to ten (5-10) subtasks.The specific course learning outcomes associated with this assignment are:Describe the methods and best practices in implementing process change in IT organizations.Describe the role and methods of technology-induced process improvement in organizations.Use technology and information resources to research issues in information systems.Write clearly and concisely about leadership issues and strategic insight of the Information systems domain using proper writing mechanics and technical style
