Zaklestskaia et al. (2009) studied college students’ alcohol-impaired (AI) driving behavior. The authors collected information on driving behavior, drinking behavior, demographics, and personality traits among 1587 students. Table 12.22 summarizes the age distribution among those reporting and not reporting AIbehavior. Is there a significant difference in the age distribution for the two groups? If so, comment on the pattern of the difference.
