How do you determine these?

5. In the U.S., the National Health and Nutrition Examination Survey (NHANES) is a national surveillance study collecting comprehensive health data from a sample of individuals representing the country's noninstitutionalized population. According to NHANES data collection from 2015-2016, the prevalence of obesity among U.S. children and adolescents 2- to 19-year-old was 18.5%. Suppose ten individuals within this age range are randomly selected for a study on pediatric obesity. Find the probability that exactly three of them would be classified as obese. a. 20.1% b. 19.6% c. 18.1% d. 18.5% e. 18.9% 6. Iron is a nutrient important for oxygen transport. The recommended daily allowance (RDA) of iron for adult females aged 19-50 is 18mg. Too much or too little iron in your diet can lead to health issues like liver problems, anemia, and heart damage. A hypothesis test is to be performed to decide whether adult females are getting less than the RDA of iron. Suppose 50' 4 adult females are selected and iron intakes had a sample mean of 14.8 mg and a sample standard deviation of 4.2 mg. Based on the research question, what is the null hypothesis? H * 18 M 2 18 M
