Quizplus · Accepted Answer

A prediction interval is used to estimate the range of values where the dependent variable is likely to fall given a certain value of the independent variable. It provides an interval estimate for the true value of y (the dependent variable) corresponding to a specific value of x (the independent variable). Therefore, choice A is the correct answer. Choices B, C, and D are incorrect as they do not accurately describe what a prediction interval is.
