Suppose we have the following data: • monthly revenue of a retail store (million dollars) • monthly advertising budget (million dollars) • location (the values for location are Midwest, US Non-Midwest, and International. Suppose we create the model below (which is separated onto several lines to make easier to read) Predicted average Revenue (millions)- 52 + 1.2 (budget) + 3.75(Midwest) 1.11(International) - 0.1 (budget) (Midwest) + 0.9" (budget) (International) If we were to graph this model, where the x-axis is advertising budget and the y-axis is predicted average revenue, what would happen?

Question
Suppose we have the following data:
• monthly revenue of a retail store (million dollars)
• monthly advertising budget (million dollars)
• location (the values for location are Midwest, US Non-Midwest, and
International.
Suppose we create the model below (which is separated onto several lines to make
easier to read)
Predicted average Revenue (millions)-
52
+ 1.2 (budget)
+ 3.75(Midwest)
1.11(International)
0.1 (budget) (Midwest)
+ 0.9"(budget) (International)
If we were to graph this model, where the x-axis is advertising budget and the y-axis is
predicted average revenue, what would happen?
There will be three parallel lines, where the line for Midwest will be on the top,
the line for US Non-Midwest will be in the middle, and the line for International
will be the lowest line. All three lines are parallel with slope 1.2
There will be two non-parallel lines, where the line for Midwest will be decreasing
and the line for International will be decreasing.
There will be three non-parallel lines, where all three lines will have an increasing
trend, and the International trend will have the steepest (highest) slope.
None of the above.
