The Kyoto Protocol was signed in 1997, and required countries to start reducing their carbon emissions. The protocol became enforceable in February 2005. The table contains a random sample of CO2 emissions from different countries. Compute a 99% confidence interval to estimate the population mean CO2 emission. Round final answers to three decimal places. CO2 Emissions (metric tons per capita) 7.9 5.87 9.16 8.49 3.71 5.57 4.9 8.9 2.86 4.56 4.14 3.57 6.19 5.78 2.25 7.43 2.24 8.89 6.09 4.2 6.72 4.87 4.98 6.59 6.14 With % confidence, it can be stated that the true population mean CO2 emission for all participating countries is between
