Mean of the sampling distribution

The mean of a sample that you take from the population will never be very far away from the population mean (provided that you randomly sample from the population). Furthermore, the mean of the sampling distribution, that is the mean of the mean of all the samples that we took from the population will never be far away from the population mean. Let's observe this in practice.
