The question asks for the variance of the mean (sample average) of a set of n independent and identically distributed random variables. Key concept: If X1, X2, ..., Xn are IID with variance Var(X) = sigma^2, then the sample mean X̄......Login to view full explanation

What's the variance of the average of n points of  random variables X. All X's are independent and identically distributed. That is, what's V( ¯ X ), for i = 1 to n? ____________________________________________________ (reminder: )

Consider the likelihood of an i.i.d. sample from a Bernoulli population with parameter p L(x1,...,xT)= T ∏ t=1pxt(1−p)1−xt. If you estimate the parameter p using a Maximum Likelihood estimator, you obtain the point estimate ˆ p = 1 T ∑ T t=1 xt, which corresponds to the sample mean. We know that for a Bernoulli random variable the expected value and the variance are 𝔼(xt)=p, 𝕍(xt)=p(1−p). Using this information, what is the variance of the estimator 𝕍( ˆ p )?
