Example: Central limit theorem; sample of n = 5 68 73 70 62 63 The mean of the sample is an estimate of the population mean. It might not be a very precise estimate, since the sample size is only 5. Example: Central limit theorem; mean of a small sample mean = (68 + 73 + 70 + 62 + 63) / 5 mean = 67.2 years See more The central limit theorem relies on the concept of a sampling distribution, which is the probability distribution of a statistic for a large number of samplestaken from a population. … See more Fortunately, you don’t need to actually repeatedly sample a population to know the shape of the sampling distribution.
