Answer the following true or false questions about statistics. 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. b. Among the class of unbiased estimators for µ, the one which has the smallest standard error is considered as the best estimator for H. c. If the computed interval estimate for µX-pY contains positive values only then we are highly confident that the mean of X is greater than the mean of Y.
