In 1945 1,100 adult Americans were asked if they abstain from alcoholic beverages and 363 indicated that they were total abstainers. A recent pole asked 1,100 adult Americans if they abstain from alcoholic beverages, of which 396 indicated that they were total abstainers. Based on these two surveys, has the proportion of adult Americans who totally abstain from alcohol changed? Use alpha = 0.05. (Remember: You want to keep the difference positive!!) Calculate the proportion of abstainers from 1945 (enter as 0.xx): Calculate the proportion of abstainers from the recent pole (enter as 0.xx): Do you pool the porportions? (enter yes or no) Using minitab: State the test statistic: (enter as x.xx) State the p-value: (enter as 0.xxx) Is there evidence to show that the proportion has changed? (enter yes or no)
