Using the Bonferroni Test

Using the Bonferroni Test Shown below are partial results from using the Bonferroni test with the sample data from Exercise 14. Assume that a 0.05 significance level is being used.

a. What do the displayed results tell us?

b. Use the Bonferroni test procedure to test for a significant difference between the mean amount of greenhouse gas emissions from six-cylinder cars and the mean from eight-cylinder cars. Identify the test statistic and either the P-value or critical values. What do the results indicate?

Exercise 14.

Car Emissions Listed below are measured amounts of greenhouse gas emissions from cars in three different categories (from Data Set 16 in Appendix B). The measurements are in tons per year, expressed as CO2 equivalents. Use a 0.05 significance level to test the claim that the different car categories have the same mean amount of greenhouse gas emissions. Based on the results, does the number of cylinders appear to affect the amount of greenhouse gas emissions?
