Note on how to present your work:

1. Use Excel to do the calculations, but summarize      your results and answer all questions in a Word document. Each numerical answer reported in your Word document should      have a reference to where in the Excel spreadsheet I can find your      calculations. Use only one Excel spreadsheet, but different tabs for your      calculations.
2. Make your “deliverables” professional looking –      as if you could show them to an investment banker in order to land an      internship/job. Graphs are recommended to support your narrative.
3. Cite your sources in the      Word document.
4. Submit your report (Word      document and Excel file) by April 22, 11:59 pm EST through Assignments in Classes. Your group number should be the first part of the name of      each submitted document (e.g. Group 1_report.docx; Group      1_calculations.xlsx; etc.).
