​The general form of an interval estimate of a population mean or a population proportion is the _____ plus and minus the _____.
A) ​population mean, standard error
B) population proportion, standard error
C) ​point estimate, margin of error
D) ​planning value, confidence coefficient

Quizplus · Accepted Answer

An interval estimate consists of a point estimate (such as a sample mean or sample proportion) plus and minus a margin of error. This margin of error represents the degree of uncertainty in the estimate and is often determined by the confidence level desired for the estimate. Therefore, the correct option is C, which identifies "point estimate, margin of error" as the terms involved in an interval estimate.
