Teen obesity: The 2013 National Youth Risk Behavior Survey (YRBS) reported that 13.7% of U. S. students in grades 9 through 12 who attend public and private school were obese. After seeing extensive efforts to educate parents and teens on healthy lifestyles, we want to know if the proportion has decreased this year. We select a random sample of 200 U. S. students and find that 11% are obese.

After performing the hypothesis test for p = 0.137 versus p < 0.137, we obtain a P‑value of 0.133. Which of the following interpretations of the P‑value is correct?

a. There is a 13.3% chance that 11% of U. S. students in grades 9 through 12 who attend public and private school were obese this year.
b. There is a 13.3% chance that 13.7% of U. S. students in grades 9 through 12 who attend public and private school were obese this year.
c. There is a 13.3% chance that 11% of U. S. students in grades 9 through 12 who attend public and private school were obese this year if 13.7% were obese in 2013.
d. There is a 13.3% chance that a sample of 200 U. S. students in grades 9 through 12 who attend public and private school will have 11% or fewer obese students if 13.7% of the population is obese this year.
