Recognising a central limit theorem problem means spotting a question about:
AMeans or sums of samples
BA single observation
CThe largest value seen
DThe order of the data
Answer & Solution
Correct answer: A. Means or sums of samples
1. The theorem describes the behaviour of statistics computed from samples.
2. The task is to recognise central limit theorem problems.
3. If the original population is far from normal, more observations are needed for the sample means or sums to be normal.
4. So the theorem covers both averages and totals of a sample.
5. A question about one individual observation is governed by the population distribution instead.
