Question

Quizplus · Accepted Answer

A point estimate is a single numerical value that is used as an estimate of a population parameter. Therefore, D is the correct choice. A parameter is a value that describes a characteristic of a population, and a population parameter specifically refers to a parameter that describes a population. While A and B are not incorrect, they are not as specific to the concept described in the question as D is.
