Textbook Problem

A set of n = 25 pairs of scores (X and Y values) produces a regression equation of Ŷ = 3X – 2.Find the predicted Y value for each of the following X scores: 0, 1, 3, −2.

To determine

To find: The predicted Y values for the given X scores.

Explanation

Given info:

The data represents the regression equation Y^=3X2 for a set of n=25 pairs of scores (X and Y values). And the X scores are given as 0, 1, 3, -2.

Calculation:

The given regression equation is,

Y^=3X2

Predicted Y values:

Substitute the given X scores in the given regression equation for getting the predicted Y values
