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.

Question

Quizplus · Accepted Answer

Since the regression equation is y = 16 + 2.3x, we can determine that the slope of the line (i.e. the increase in y for each unit increase in x) is 2.3. Therefore, an increase in x of 2.0 would lead to an expected increase in y of 2.0 x 2.3 = 4.6. So, the statement is true.
