Question
According to the Centers of Disease Control, about 22% of American young people between the ages of 12 and 19 are obese.
A student claims that the students his local schools are in better shape than the national average, so their proportion of obese students is less than 22%.
Which are the appropriate null and alternative hypotheses for this study?
- H0: p = 22%, H1: p < 22%
- H0: p = 22%, H1: p ≠ 22%
- H0: p ≠ 0, H1: p = 0
- H0: p = 22%, H1: p > 22%
Suppose that the result of the statistical is to reject H0.
Which is the proper conclusion?
- There is not sufficient evidence to conclude that the students at his local schools have a smaller true proportion of obese students.
- There is sufficient evidence to conclude that the students his local schools have a smaller true proportion of obese students.
- There is not enough information to answer this question.
