Answer #1

Solution:-Given satemetn is True

Expalaination:- The sample variance formula makes it an unbiased estimator it is a true statement why beacause In statistics, the bias (or bias function) of an estimator is the difference between this estimator's expected value and the true value of the parameter being estimated. An estimator or decision rule with zero bias is called unbiased. Otherwise the estimator is said to be biased.The sample variance is an estimator for the population variance. When applied to sample data, the population variance formula is a biased estimator of the population variance

Answer true or false: We saw that the sufficient conditions for a consistent estimator included the condition that the limit of the variance of the estimator must be zero as n increases. Since the formula for the variance of our estimated betahat2 does not include an n in our denominator, unlike the variance of the sample mean, we can prove that it is asymptotically unbiased, but we cannot claim that it is consistent.

To show that an estimator can be consistent without being unbiased or even asymptotically unbiased, consider the following estimation procedure: To estimate the mean of a population with the finite variance σ2, we first take a random sample of size n. Then we randomly draw one of n slips of paper numbered from 1 through n, and if the number we draw is 2, 3,..., or n, we use as our estimator the mean of the random sample; otherwise, we...
