# Using a Regression Equation

Question: Find (a) explained variation, (b) unexplained variation, (c) total variation, (d) coefficient of determination, (e) standard error of estimate Se. In each case, there is sufficient evidence to support a claim of a linear correlation so that it is reasonable to use the regression equation when making predictions.

Scenario: Global warming;

Listed below are concentrations (in parts per million) of CO2 and temperatures (in degree Celsius) for different years.

CO2: 314, 317, 320, 326, 331, 339, 346, 354, 361, 369

Temperature: 13.9, 14.0, 13.9, 14.1, 14.0, 14.3, 14.1, 14.5, 14.5, 14.4
