In a Gallup poll conducted July 7–10, 2014, 45% of Americans said that they actively try to include organic foods into their diets (www.gallup.com). In a recent sample of 2100 Americans, 1071 said that they actively try to include organic foods into their diets. Is there significant evidence at a 1% significance level to conclude that the current percentage of all Americans who will say that they actively try to include organic foods into their diets is different from 45%? Use both the p-value and the critical-value approaches.
