The Kyoto Protocol was signed in 1997, and required countries to start reducing their carbon emissions. The protocol became enforceable in February 2005. In 2001, the mean CO2 emission was 4.93 metric tons per capita. Is there enough evidence to show that the mean CO2 emission is lower in 2008 than in 2001? State the Type I and Type II errors in this case. State the Type I error. Concluding that the mean CO2 emissions haven't changed when the mean CO2 emission in 2008 is less than 4.93 metric tons per capita (2001 value). Concluding that the mean CO2 emission in 2008 is greater than 4.93 metric tons per capita (2001 value) when the emissions haven't changed. Concluding that the mean CO2 emissions haven't changed when the mean CO2 emission in 2008 is greater than 4.93 metric tons per capita (2001 value). Concluding that the mean CO2 emission in 2008 is less than 4.93 metric tons per capita (2001 value) when the emissions haven't changed. State the Type II error. Concluding that the mean CO2 emissions haven't changed when the mean CO2 emission in 2008 is greater than 4.93 metric tons per capita (2001 value). Concluding that the mean CO2 emissions haven't changed when the mean CO2 emission in 2008 is less than 4.93 metric tons per capita (2001 value). Concluding that the mean CO2 emission in 2008 is greater than 4.93 metric tons per capita (2001 value) when the emissions haven't changed.
