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 40 countries were collected. Is there enough evidence to show that the mean CO2 emission is different in 2010 than in 2004? State the random variable, population parameter, and hypotheses. a.

The Food and Drug Administration (FDA) regulates the amount of mercury in consumable fish, where consumable fish should only contain at most 1mg/kg of mercury. In Florida, bass fish were collected in 52 different lakes to measure the amount of mercury in the fish from each of the 52 lakes. Do the data provide enough evidence to show that the fish in all Florida lakes have higher mercury than the allowable amount? State the random variable, population parameter, and hypotheses. a.
