Let X_1,X_2,……… X_10 be an independent random sample of size n=10 from a population having mean μ=8 and variance σ^2=4. Consider the following estimators of μ: μ ̂_1=X ̅ and μ ̂_2=2X_1-X_2. Check unbiasedness of above estimators. If biased find the amount of bias. Determine the variance of the estimators. Find the relative efficiency and identify the best estimators.
