For recent UN data from 39 countries on y = per capita carbon dioxide emissions (metric tons per capita) and x = per capita gross domestic product (GDP, in dollars), the prediction equation was y = 1.26 + 0.346a:

(a) Predict y at the (i) minimum x-valuc of 0.8, (ii) maximum x = 34.3.

(b) For the U.S., x = 34.3 and y = 19.7. Find the predicted carbon dioxide response value. Find the residual and interpret.

(c) For Switzerland, x = 28.1 and y = 5.7. Find the predicted carbon dioxide response value and residual. Interpret.
