Here's some data from a business that routinely tests different percentage off ideas to various customer segments.
Your job is "fill in the blanks" ... what would have happened if you offered 50% off to a Good customer? What would have happened if you offered 10% off to a Poor customer?
Fill in each of the empty cells. Adjust the cells you don't like that exist in the table. Share your methodology and results with me ... write up your solution ... I'll publish good predictions, ok?
