Question

Given a regression equation of  = 16 + 2.3x we would expect that an increase in x of 2.0 would lead to an average increase of y of 4.6.

Quizplus · Accepted Answer

According to the regression equation, for every one unit increase in x, y is expected to increase by 2.3 units. Therefore, for a two unit increase in x (from x to x+2), we would expect y to increase by 2.3 * 2 = 4.6 units.
