# Theory of Estimation

A random sample x1, x2, x3, x4, x5 of size 5 is drawn from a normal population with unknown mean. Consider the following estimators to estimate mean. (i) t1=(x1+x2+x3+x4+x5)/5 (ii) t2=(x1+x2)/2+x3 (iii) t3=(2×1+x2+Kx3)/3 Q1. find K Q2. are t1 and t2 unbiased? Q3. which is the most efficient estimator?
