In 1948, 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, 440 indicated that they were total abstainers. In a recent survey, the same question was asked of 1100 adults and 374 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 1948 survey and the recent survey who were total abstainers are 0.4 and 0.34, respectively. (Round to three decimal places as needed.)
(b) Find the test statistic for this hypothesis test. (Round to 2 decimal places).
