Question: A simple regression produces the regression equation Y-bar = 5X + 7. a. If we add 2 to all the X values in the data

A simple regression produces the regression equation Y-bar = 5X + 7.

a. If we add 2 to all the X values in the data (and keep the Y values the same as the original), what will the new regression equation be?

b. If we add 2 to all the Y values in the data (and keep the X values the same as the original), what will the new regression equation be?

c. If we multiply all the X values in the data by 2 (and keep the Y values the same as the original), what will the new regression equation be?

d. If we multiply all the Y values in the data by 2 (and keep the X values the same as the original), what will the new regression equation be?
