Among unbiased estimators, the one with the smaller variance is more efficient (precise). μ̂₁ has variance σ²/4. μ̂₂ has variance (1/64)σ² + (1/64)σ² + (1/16)σ² + (1/4)σ² = σ²*(1/32+1/32+1/16+1/4) = σ²*(0.03125+0.03125+0.0625+0.25) = 0.375σ², which is larger than σ²/4 = 0.25σ². Therefore μ̂₁ is more efficient.
