According to a survey in PARADE magazine, almost half of parents say their children's weight is fine. Only 9% of parents describe their children as overweight. However, the American Obesity Association says the number of overweight children and teens is at least 15%. Suppose that you sample n = 750 parents and the number who describe their children as overweight is x = 68.
a. How would you test the hypothesis that the proportion of parents who describe their children as overweight is less than the actual proportion reported by the American Obesity Association?
b. What conclusion are you able to draw from these data at the α = .05 level of significance?
c. What is the p-value associated with this test?
