A) An estimator is a sample statistic used to estimate a population parameter, while an estimate is the value(s) assigned to a population parameter based on the value of a sample statistic.
B) An estimator is the value of a sample statistic used to estimate a population parameter, while an estimate is an interval where one is confident to a certain percent that the value of interest is in the interval.
C) An estimator is the value(s) assigned to a population parameter based on the value of a sample statistic, while an estimate is a sample statistic used to estimate a population parameter.
