You Recall from One of Your Earlier Lectures in Macroeconomics

Essay

You recall from one of your earlier lectures in macroeconomics that the per capita
income depends on the savings rate of the country: those who save more end up
with a higher standard of living.To test this theory, you collect data from the
Penn World Tables on GDP per worker relative to the United States (RelProd)in
1990 and the average investment share of GDP from 1980-1990 (sK ),
remembering that investment equals saving.The regression results in the
following output: $$\begin{array} { l } \widehat { \text { RelProd } } = 0.08 + 2.44 \times s _ { K } , R ^ { 2 } = 0.46 , S E R = 0.21 \\\quad\quad\quad\quad\quad( 0.04 ) ( 0.38 ) \\\end{array}$$ (a)Interpret the regression results carefully.
