When does warmer help the process?
Warm the process at low pressure
In the invented chemical process, warming can help at one pressure and hurt at another. Botie needs the supplied product term to represent that dependence.
BOTIE
The inputs we are comparing
Temperature change
Cooler at low pressure
-1
Warmer at low pressure
1
Pressure change
Same in both cases
-3
Result for cooler at low pressure
8
A larger temperature change under lower pressure
This check uses the pieces from “Combine the process's separate and joint effects”.

Use a number, text, or an array matching the requested result. For a matrix, put each row in brackets. Saving your prediction runs your current construction on these inputs and checks the earlier examples too.
Build a construction in the workspace above first. This case will test those pieces.
Why can the sign of the standalone temperature coefficient mislead when an interaction is present?
Ask which other inputs are held fixed before interpreting a feature's effect on a prediction.
This is a small construction problem. The lesson explains the assumptions and the parts of the full method that this example leaves out.
