9.1.4 - Hypotheses

9.1.4 Hypotheses: null, alternate, experimental; directional and non-directional.

Use - hypotheses to connect the rule to the data and decision in the question.

This matters because - hypotheses determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - hypotheses to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Hypotheses is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
