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, 363 indicated that they were total abstainers. In a recent survey, thesame question was asked of 1100 adults and 286 indicated that they were total abstainers. Complete parts (a) and (b) below.(a) Determine the sample proportion for each sample.The proportions of the adults who took the 1945 survey and the recent survey who were total abstainers are and , respectively.(Round to three decimal places as needed.)
