A survey was conducted to determine whether a driver's propensity to engage in road rage is related to his or her income. The mean road rage scores of drivers in three income groups were labeled A, B, and C. Use the partial ANOVA summary table given below to complete parts a through c below.

Identify the null and alternate hypotheses for the test given in the ANOVA results. He H What conclusion can you draw from the ANOVA results? V the null hypothesis. There is V evidence to conclude that V of the means are significantly different from each other. b. A multiple comparisons of means procedure was applied to the data using an experimentwise error rate of 0.05. Explain what the O.05 means. Choose the correct answer below. O A.
