You are given three estimators for the population mean μ: μ̂₁ = X̄ + 0.01n, μ̂₂ = X̄ - X̄/n, μ̂₃ = X̄ - 1/n. X̄ is the sample mean, and n is the sample size. Give the definition of an unbiased estimator and compute the bias in each estimator. Which of the three estimators has the smallest bias? Refer to this estimator below as μ̃.
