A survey was given to college students nationwide. The question asked was: "Do you completely abstain from alcohol or not?" Of a random sample of 212 students at community colleges (Group 1), 87 claimed to completely abstain. Of a random sample of 390 students at 4-year colleges (Group 2), 103 claimed to completely abstain. At =0.10, is there evidence to claim a difference in the two proportions exists?
