THE NEXT QUESTIONS ARE BASED ON THE FOLLOWING INFORMATION:
Let X1,X2,X3,and X4 be a random sample of observations from a population with mean μ and variance σ2.Consider the following two point estimators of μ: 
1 = 0.10 X1 + 0.20 X2 + 0.40 X3 + 0.30 X4,and 
2 = 0.25 X1 + 0.25 X2 + 0.30 X3 + 0.20 X4
-Show that both the estimators are unbiased.
