A regression line for predicting Internet usage (%) for 39 countries is y^ = -3.61 + 1.55x, where x is the per capita GDP, in thousands of dollars, and y is Internet usage. Interpret the residual for one of the 39 countries with per capita GDP of $15,000 and actual Internet use of 20 percent. A) The actual Internet usage for this country is 0.36% higher than expected from the regression equation. B) The actual Internet usage for this country is 3.6% higher than expected from the regression equation. C) The actual Internet usage for this country is 0.36% lower than expected from the regression equation. D) The actual Internet usage for this country is 3.25% higher than expected from the regression equation. E) The actual Internet usage for this country is 3.25% lower than expected from the regression equation.
Homework Answers
here since residual =actual value -predicted value =20-(-3.61+1.55*15)=0.36 %
option A is correct
A) The actual Internet usage for this country is 0.36% higher than expected from the regression equation

It wouldn’t be appropriate because the heart disease is
in -83.975.
