What is the main idea of the weak law of large numbers?
A) As the number of observations in a sample goes to infinity then the sample average converges to the mean of the population.
B) As the number of observations in a sample goes to infinity then the sample average is the mean of the population.
C) If your sample reaches some threshold number of observations, then the sample average is indistinguishable from the mean of the population.
D) It is impossible to know the average of a sample unless the mean of the population is large enough.
