How does an interval estimator differ from a point estimator? A point estimator

Question

How does an interval estimator differ from a point estimator? A point estimator may produce very biased results, while an interval estimator never has such a feature. An interval estimator provides a range of values that always include the estimated population parameter. If a point estimator fails to produce an unbiased result, then an interval estimator secures such a result. An interval estimator provides a range of values for the estimated population parameter rather than a single value provided by a point estimator.

Explanation / Answer

How does an interval estimator differ from a point estimator?

A interval gives you a range of values; a point estimate gives a single value. Hence,

An interval estimator provides a range of values for the estimated population parameter rather than a single value provided by a point estimator. [ANSWER, D]
