In 2011, 17 percent of a random sample of 200 adults in the United States indicated that they consumed at least 3 pounds of bacon that year. In 2016, 25 percent of a random sample of 600 adults in the United States indicated that they consumed at least 3 pounds of bacon that year. Assuming all conditions for inference are met, which of the following is the most appropriate test statistic to use to investigate whether the proportion of all adults in the United States who consume at least 3 pounds of bacon in 2016 is different from that of 2011? 0.17-0.25 (A) 2 = (0.17) (0.83) (0.25) (0.75) 200 600 0.17-0.25 (B) (0.17) (0.83) (0.25) (0.75) 600 200 0.17-0.25 U (0.21)(0.79) (200 + 600) 0.17-0.25 (D) 2= (0.23) (0.77) (200 + 600) 0.17-0.25 (0.50) (0.50 ) (200 + 800) age 6 of 42 AP Statistics
