QUESTION 3 (c). A Readers Digest/Gallup Survey on the drinking habits of Americans estimated the percentage of adults across the country who drink beer, wine, or hard liquor, at least occasionally. Of the 1516 adults interviewed, 985 said that they drank. (i). Determine a 95% confidence interval for the proportion, p, of all Americans who drink beer, wine, or hard liquor, at least occasionally. (ii). Determine a 90% confidence interval for the proportion, p, of all Americans who drink beer, wine, or hard liquor, at least occasionally. (iii).Interpret your results from part (i) and part (ii) .What can you conclude from the interpretation of these results. (iv). Determine a 95% confidence interval for the proportion, p, of all Americans who dont drink beer, wine, or hard liquor, at least occasionally. (v). Determine a 90% confidence interval for the proportion, p, of all Americans who dont drink beer, wine, or hard liquor, at least occasionally. (vi).
