Question

According to the Centers of Disease Control, about 20% 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 20%.

Which are the appropriate null and alternative hypotheses for this study?
- H₀: p = 20%, H₁: p < 20%
- H₀: p = 20%, H₁: p > 20%
- H₀: p = 20%, H₁: p ≠ 20%
- H₀: p ≠ 0, H₁: p = 0
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.
