(i) Point estimator (ii) Interval estimator
(iii) Unbiased estimator (iv) None of these

2. A property of a point estimator that occurs whenever larger sample sizes tend to
provide point estimates closer to the population parameter is known as,
(i)	Unbiasedness (ii) efficiency (iii) consistency (iv) None of these

(iii) Consistent, unbiased (iv) None of these
4. Given two unbiased point estimators of the same population parameter, the point
estimator with the smaller variance is said to have,
(i) Smaller relative efficiency (ii) greater relative efficiency
(iii) Smaller consistency (iv) larger consistency

5. MLE is always need not be,
