Interpret the slope of the line. For a 1 metric ton increase in US emissions, non-US emissions will, on average, increase by 22.8 metric tons. For a 1 metric ton increase in non-US emissions, US emissions will, on average, decrease by 0.96 metric tons. For a 1 metric ton increase in non-US emissions, US emissions will, on average, increase by 22.8 metric tons. For a 1 metric ton increase in US emissions, non-US emissions will, on average, decrease by 0.96 metric tons. We should not interpret the slope in this problem. Interpret the �-intercept of the line. On average, when �=0, non-US emissions are -0.96 metric tons. On average, when �=0, US emissions are -0.96 metric tons. On average, when �=0, US emissions are 22.8 metric tons. On average, when �=0, non-US emissions are 22.8 metric tons. We should not interpret the �-intercept in this problem. We should interpret the �-intercept, but none of the above are correct.

ANSWER ALL QUESTION

Interpret the slope of the line.

  • For a 1 metric ton increase in US emissions, non-US emissions will, on average, increase by 22.8 metric tons.
  • For a 1 metric ton increase in non-US emissions, US emissions will, on average, decrease by 0.96 metric tons.
  • For a 1 metric ton increase in non-US emissions, US emissions will, on average, increase by 22.8 metric tons.
  • For a 1 metric ton increase in US emissions, non-US emissions will, on average, decrease by 0.96 metric tons.
  • We should not interpret the slope in this problem.



Interpret the �-intercept of the line.

  • On average, when �=0, non-US emissions are -0.96 metric tons.
  • On average, when �=0, US emissions are -0.96 metric tons.
  • On average, when �=0, US emissions are 22.8 metric tons.
  • On average, when �=0, non-US emissions are 22.8 metric tons.
  • We should not interpret the �-intercept in this problem.
  • We should interpret the �-intercept, but none of the above are correct.
Carbon dioxide is produced by burning fossil fuels such as oil and natural gas, and
been connected to global warming. The following output presents the average am
(in metric tons) of carbon dioxide emissions for the years 1999-2006 per person in
United States and per person in the rest of the world in an effort to determine if r
US per person emissions can help predict US per person emissions.
