 1. A confidence interval is an interval estimate for which there is a specified degree of certainty that the actual value of the population parameter will fall within the interval.

 2. An interval estimate is an estimate of the range for a sample statistic.

 3. Knowing that an estimator is unbiased only assures us that its expected value equals the parameter, but it does not tell us how closely the estimator is to the parameter.

 4. An unbiased estimator is said to be consistent if the difference between the estimator and the parameter grows smaller as the sample size grows larger.
