Question

predicted carbon dioxide concentration =
311.662 + 1.43866 x (years elapsed since 1959).


Step 1:
Global warming may be due to increased concentrations of greenhouse gases such as carbon dioxide (co2co2). Here are data from the National Oceanic and Atmospheric Administration Web site (www.noaa.gov), where co2co2 is measured in parts per million by volume:




A regression line for predicting carbon dioxide from time is

predicted carbon dioxide concentration =
311.662 + 1.43866 x (years elapsed since 1959).


(Fill in the blanks below and give your answers to 4 decimal places.)

What is the slope of this line? ____

For each additional year the amount of carbon dioxide is increasing by ____ parts per million by volume.



Answer 1______
Answer 2______ CO, 315.98 324.62 336.78 352.90 368.14 387.35 Year 1959 1969 1979 1989 1999 2009

Explanation / Answer

predicted carbon dioxide concentration = 311.662 + 1.43866 x

What is the slope of this line? 1.4387

2) predicted carbon dioxide concentration = 311.662 + 1.43866 * 1 = 313.10066

For each additional year the amount of carbon dioxide is increasing by 313.10066 parts per million by volume.
