The Kyoto Protocol was signed in 1997, and required countries to start reducing their carbon emissions. The Do is unknown protocol became enforceable in February 2005. In 2004, the mean carbon dioxide emission was 4.87 metric On(1 - ) 2 10 capita, The table below contains the carbon dioxide emissions from a random sample of In(1 - p) 2 10 from a recent study. Is there enough evidence to show that the mean carbon dioxide emission is now lower Inp 2 10 than it was in 2004? Test at the 5% level. no outliers in the data On 2 30 or normal population carbon dioxide emissions in metric tons per capita ON 2 20n 5.36 On(p) 2 10 1.42 Do is known outliers in the data 1.45 2.44 Check those assumptions: 9.11 1.
