if the non us emissions differe from 0.2 from on year to the next by how much would you predict the US emissions to differ? round the answer to four decimal places.

Answer 1

We can see that the regression equation is given by

y^ = -1.9736x + 26.2736

if emissions differ from 0.2

i.e x = 0.2

y^ = -1.9736*0.2 + 26.2736

= -0.3947 + 26.2736

y^ = 25.8789

The U. S emissions would differ by 25.8789
