duh

no. your sample average X_bar would have a standard deviation approaching zero when you roll a dice many times. You're a ****ing idiot. The set of values is different from the mean of the set.

A set of independently determined means has a variance which approaches 0 as the number of trials in each determination of the mean increases. Any given set of actual trials has a variance which approaches 35/12

You're like a ****ing child.
