According to the Central Limit Theorem (CLT), regardless of the shape of the original population, the distribution of sample means will approach a Normal Distribution as:
Test yourself: pick an answer
Reveal answer & explanation
Correct answer: B) The sample size (n) becomes sufficiently large (usually n ≥ 30).
Explanation
The CLT is a fundamental pillar of statistics, allowing us to use normal distribution techniques even on non-normal populations, provided the sample size is large enough.
