will result in an increase in the length of the interval estimate. A. True B. False 2. The unbiased estimator of a particular parameter is unique, i.e. there can only be one unbiased estimator. A. True B. False 3. The confidence level can be interpreted as the probability that the interval estimate encloses the true population parameter. A. True B. False 4. The sample mean is the most efficient estimator of μ when sampling from the normal distribution. A. True B. False 5. If the standard error of the estimator is close to 0 then this indicates that the values of this statistic from one sample to the other are close to the value of the parameter it is estimating. A. True B. False 6. Among the class of unbiased estimators for µ, the one which has the smallest standard error is considered as the best estimator for μ A. True B. False
