Question

Find the equation of the regression line for the given data. Then construct a scatter plot of the given x-values, if meaningful. The table below shows the heights (in feet) and the number of stories of Height, Stories, y data and draw the regression line. (The pair of variables have a signiicant correlation.)

Answer 1

The fitted regression equation is

   , based on the data.

The correct plot looks like

So the correct option is (D)

When x = 498 the predicted value of y is 0.051*498 +13.99 = 40 ( approximately)

So the correct option is (B).
