Question
In 1945, an organization surveyed 1100 adults and asked, "Are you a total abstainer from, or do you on occasion consume, alcoholic beverages?" Of the 1100 adults surveyed, 352 indicated that they were total
abstainers. In a recent survey, the same question was asked of 1100 adults and 275 indicated that they were total abstainers. Complete parts (a) and (b) below.
(b) Has the proportion of adults who totally abstain from alcohol changed? Use the a = 0.01 level of significance.
