D) All of these options

Question

Quizplus · Accepted Answer

A point estimate is a single value estimate of the value of a population parameter. Option A is incorrect because a point estimate provides a single value, not a range. Option C is incorrect because an unbiased estimator is one that, on average, gives a correct estimate of the population parameter, and has nothing to do with the standard deviation of the point estimate.
