Central Limit Theorem

Question 1

Central limit theorem - 2 + 2

Answer 1

• Sample of size n > 30 from population with mean μ and standard deviation σ
• X Bar, or sample mean has approximately a normal distribution
• • mean = μ
• • Standard deviation = σ / √n

Question 2

CLT for normal population - 1

Answer 2

• The difference is that the sample can be of any size, instead of n > 30
