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. Table below contains a random sample of carbon dioxide emissions from 36 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? Test at the 3% level. P: Parameter Carbon Dioxide Emissions (in metric tons per capita) 4.56 5.94 5.93 2.62 7.84 2.26 2.27 0.79 1.8 3.45 2.86 5.85 7.48 3.46 0.06 1.46 1.45 7.32 0.2 1.42 0.78 1.35 3.45 5.36 2.45 6.72 7.93 3.02 5.86 1.36 6.02 2.44 0.28 0.14 0.86 2.87
AA What is the correct parameter symbol for this problem? What is the wording of the parameter in the context of this problem? Select an answer H: Hypotheses Fill in the correct null and alternative hypotheses: Ho: ? ? 8 HA ? B A: Assumptions ? 8 Do is known Since Select an answer information was collected from each object, what conditions do we need to check? Check all that apply. n(1-P) ≥ 10 Doutliers in the data n(p) ≥ 10 no outliers in the data np > 10 ON 220n o is unknown n(1-P) ≥ 10 On ≥ 30 or normal population Check those assumptions: 1. Is the value of a known?? 8 metric tons per capita 2. Are there any outliers? Select an answer metric tons per capita
3. n = Is it reasonable to assume the population is normally distributed? Select an answer N: Name the test The conditions are met to use a Select an answer which is? B T: Test Statistic The symbol and value of the random variable on this problem are as follows (round to 4 decimal places): (C The formula and value of the test statistic are as follows: Round the mean and standard deviation to 4 decimal places and the final answer to 2 decimal places. X-H P-value= O: Obtain the P-value Report the final answer to 4 decimal places. It is possible when rounded that a p-value is 0.0000 M: Make a decision Since the p-value ? 8 O S: State a conclustion There Select an answer significant evidence to conclude Select an answer metric tons per capita we Select an answer B Select an answer
