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 CO2 emission was 4.87 metric tons per capita. In 2010, the CO2 emissions for a random sample of 38 countries were collected. Is there enough evidence to show that the mean CO2 emission is lower in 2010 than in 2004? State the random variable, population parameter, and hypotheses. a. The symbol for the random variable involved in this problem is X b. The wording for the random variable in context is as follows: the mean carbon emissions of 38 randomly selected countries in 2010 ✓ c. The symbol for the parameter involved in this problem is µV d. The wording for the parameter in context is as follows: the mean carbon emissions of all countries in 2010 e. Fill in the correct null and alternative hypotheses: Ho: μ HA: H
