Assignment 1 MGT 610 Due 9/20/2020. 11:59 pm
All assignments should be written in your own words providing examples and opinions beyond the textbook or any other source that you get them from. I will be looking for more of your opinions and examples beyond definitions and just answers. For calculations show ALL your steps included calculator/Excel keystrokes and/or formulas. If using Excel remember to upload the original files so I can check your work. It is important explain and briefly discuss your final answers and what they represent, do not just provide a number answer without any work. All work should be in your OWN words NOT any others or the textbook for full credit. This applies to all assignments for the course.
