15 kg. What would the mean and standard deviation of a sample of 50 guys be if a researcher looked at their records? Solution: Given: μ = 70 kg, σ = 15 kg, n = 50 As per the Central Limit Theorem, the sample mean is equal to the population mean. Hence, μx = μ = 70 kg Now, σx = σ/(√n) = 15/√50 ≈ 2.1
