Refer to the previous exercise. Using regression, the prediction equation relatingGDP(in thousands of dollars per capita) to carbon dioxide emissions (in metric tons per capita) is Predicted CO2 = 1.93 + 0.178(GDP).

(a) What type of pattern would you expect for the points in a scatterplot for these data?

(b) In this data set, the highest CO2 value was 17.0 metric tons, for the United States. Its GDP was 53.1.

Find its predicted CO2 use, according to the regression analysis.

(c) In this data set,GDPranged from a low of 4.4 to a high of 62.9.

Find the range of predicted CO2 values.
