What does this explain? Sampling frame, Measure of central tendency, Sampling Distribution, Central Limit Theorem, or Confidence interval estimation? Suppose that the population distribution of a variable (X) has a mean (μ)and a standard deviation (σ). If you randomly draw an infinite number ofsamples from the population, and if the sample size (N) is big enough, thenthe distribution of the sample means (X) has a normal distribution with amean (μx = μ) and a standard deviation (σx =σ/√N).

Central Limit TheoremExplanation:It is the Central Limit Theorem. It explains that, regardless of…
