Use this information to answer the question.

Information from the CDC indicates the prevalence of obesity in American children ages 6-11 is 18.4%. A large school district concerned about childhood obesity started a school breakfast and lunch program 3 years ago to promote healthier choices including more fruits and vegetables. As a result, they believe the obesity rate is lower in children in their district.

To test their theory, they select a random sample of 150 students who've been enrolled in district schools for the past 3 years and found that 19 of them were obese.

What is the alternate hypothesis?

a.) H_a: < 0.184

b.) H_a:p < 0.184

c.) H_a:p < 0.127

d.) H_a:< 19

e.) H_a:p^p^ < 0.127
