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. Compute a 99% confidence interval to estimate the mean CO2 emission. Round to three decimal places. CO2 Emissions (metric tons per capita) 7 8.84 7.45 8.18 9.11 7.08 8.34 7.43 3.43 6.06 6.69 2.72 8.66 6.4 6.94 7.55 7.78 1.61 2.17 0.87 6.67 2.22 1.6 8.91 2.82 With 99 and O % confidence, it can said that the true mean CO2 emission is between
