@Cromwell523 Just a single sample of size n. I make a lot of semantic errors in this video actually, I was concentrating on getting the math right and so the quality of the English deteriorated.
What do you mean by variance of the mean? with a given number of X_i you only have one mean which is Sum(X_i/n). so it cannot have a varience.
Even in your example it should be obvious that you won´t get the right number of jellybeans within the jar just by asking an infinite number of people and i can prove that with a simple mind experiment if you are interested
Congratulations sir, you win the award for longest video title!!!

so you mean several distributions of x each with a different mean? i.e. n sample groups with n samples each?

@Cromwell523 I meant variance of the sampling distribution of the sample mean.
