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

Pressure remains -3 while temperature changes from -1 to 1. Can the positive standalone temperature coefficient guarantee a higher predicted yield?
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
Choose an explanation to test
A larger temperature change under lower pressure

This check uses the pieces from “Combine the process's separate and joint effects”.

BOTIE

Temperature rises by two units while pressure falls by one. Predict the supplied polynomial rule's output, including its interaction term.

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.
