The phenomenon of road rage has been frequently discussed but infrequently examined." so begins a report based on interviews with 1382 randomly selected drivers. the respondents' answers to interview questions produced scores on an "angry/threatening driving scale" with values between 0 and 19. does the driver's age affect road rage? here are the mean responses for three age-groups. the report says that f = 34.96 with p-value < 0.01. what is the null hypothesis for the anova f test? all age groups have the same mean response. all age groups have a different mean response. at least one age group has a different mean response. what is the alternative hypothesis for the anova f test? all age groups have the same mean response. all age groups have a different mean response. at least one age group has a different mean response. based on the sample means and the results of the anova, what do you conclude at the alpha = 0.05 level? there is sufficient evidence at the alpha = 0.05 level that all of the age groups have the same mean "road rage" score. there is sufficient evidence at the alpha = 0.05 level that the at least one of the age groups has a different mean "road rage" score. there is insufficient evidence at the alpha = 0.05 level that all of the age groups have the same mean "road rage" score. there is insufficient evidence at the alpha = 0.05 level that the at least one of the age groups has a different mean "road rage" score.
