The Kyoto Protocol was signed in 1997, and required countries to start reducing their carbon emissions. The protocol became enforceable in February 2005. In 2004, the mean carbon dioxide emission was 4.87 metric tons per capita. The table below contains the carbon dioxide emissions from a random sample of countries from a recent study. Is there enough evidence to show that the mean carbon dioxide emission is now lower than it was in 2004?
