A sample size of \(x\) is considered to be sufficient to hold Central Limit Theorem (CLT). The value of \(x\) should be:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → greater than or equal to 30
The Central Limit Theorem says that the distribution of the sample mean gets closer to a normal distribution as the sample size grows, whatever the shape of the population.
So the sample size does matter. In practice a sample is taken as large enough when n ≥ 30, so x ≥ 30.
