A Compulsory Part candidate sees a practice question on the normal distribution. What is the right judgement?
A. It is a compulsory foundation topic and must be answered with z-tables
B. It replaces standard deviation in the compulsory syllabus
C. The normal distribution belongs to Module 1, not the Compulsory Part, so check that the paper really is a compulsory paper✓ 答案
D. It is required only in Paper 1 Section B
解說
The normal distribution is extended-module probability, not compulsory content. Standard deviation remains the compulsory measure of spread. A compulsory past paper will not require a z-table.
