Question

Question Help . The data found below measure the amounts of greenhouse gas emissions from three types of vehicles. The measurements are in tons per year, expressed as CO2 equivalents. Use a 0.05 significance level to test the claim that the different types of vehicle have the same mean amount of greenhouse gas emissions. Based on the results, does the type of vehicle appear to affect the amount of greenhouse gas emissions? Click the icon to view the data. What are the hypotheses for this test? A. Ho: 11 = H2 H3 H:H *12* H3 B. Ho: 14 * H2 H3 H: =H2 = P3 C. Ho: 11 = H2 = 13 H: At least one of the means is different from the others. D. Ho: At least one of the means is different from the others. H: 14 = H2 =23 Determine the test statistic. F=(Round to two decimal places as needed.) Identify the P-value P-value =(Round to two decimal places as needed.) What is the conclusion of the test? appear to affect the amount of the null hypothesis. Conclude that the type of vehicle greenhouse gas emissions for these three types.
