In a 2016 article published in the Journal of American College Health, Heller et al. surveyed a sample of students at an urban community college. Students’ ages and frequency of alcohol use per month are recorded in the following table. Because some of the expected counts are less than 5, we should combine some groups. For this question, combine the frequencies 10 –29 days and Every day into one group. Label this group 10+ days and show your new table. Then test the new table to see whether there is an association between age group and alcohol use using a significance level of 0.05. Assume this is a random sample of students from this college.
