An organization surveyed 1,100 adults and asked, "Are you a
total abstainer from, or do you on occasion consume, alcoholic
beverages?" Of the 1,100 adults surveyed, 363 indicated that they
were total abstainers. Sixty years later, the same question was
asked of 1,100 adults and 435 indicated that they were total
abstainers. Has the proportion of adults who totally abstain from
alcohol changed? Use the a equals 0.=0.10 level of
significance.
