REPORT APPEARANCE: this should be considered a formal report which should be prepared in a professional manner. Your report should include the following:
Title Page
Make the title page professional in appearance. Name the case that you have been assigned, indicate the course, the project, your professor’s name, your names, and the due date.
Table of Contents
List all the sections with their corresponding page numbers.
Introduction
Set up the context for the report by giving background information about the area(s) in your data set and indicate the purpose of this report.
The following are some formatting guidelines that you should implement in your report:
· Use 11-12 point font size and 1.5-2 line spacing.
· Round final answers to 2 decimal places where applicable.
Statistical Findings: this section of the report should include your answers to the questions. Present your findings in a logical and organized way. Use the data set provided in Excel to complete your calculations. Note: question numbers correspond to chapter numbers.
Questions:
