N i=1 (x i x¯)2 and 1 n1 i=1 (x i x¯)2 (144) Using bias as our criterion, we can now resolve between the two choices for the estimators for the variance 2 Again, we use simulations to make a conjecture, we then follow up with a computation to verify our guess For 16 tosses of a fair coin, we know that the variance is np(1p) = 16·1.

Thus, holds for n = k 1, and the proof of the induction step is complete Conclusion By the principle of induction, it follows that is true for all n 2Z Remark Here standard induction was su cient, since we were able to relate the n = k1 case directly to the n = k case, in the same way as in the induction proofs for summation formulas. N from a distribution f (x) is a set of independently and identically variables with x i ∼ f (x) for all i Their joint pdf is f (x 1,x 2,,x n)= f (x 1) f (x 2) ··· f (x 2)= n i =1 f (x i) The sample moments provide estimates of the moments of f (x) We need to know how they are distributed Themean ¯ x.

The binomial distribution for a random variable X with parameters n and p represents the sum of n independent variables Z which may assume the values 0 or 1 If the probability that each Z variable assumes the value 1 is equal to p , then the mean of each variable is equal to 1*p 0*(1p) = p , and the variance is equal to p(1p). ) = 2x= 2, 0.
