Have you ever wondered how medical professionals give estimates for health measures such as the average cholesterol levels of a healthy man? The National Health and Nutrition Examination Survey (NHANES) is a population survey about health and nutrition that can be used to estimate information about the health of different groups in the U.S. population. In this task,you will take a sample from the 2003 NHANES survey to explore two questions. Alternatively, you could generate your own statistical questions to explore about different health measures or different subgroups of survey respondents. 1. Examine the relationships between women who are pregnant and their age, marital status, education status, and household income. What trends do you notice? 2. Are certain groups more likely to be anemic than other groups? Can you predict how much iron a person has in his or her blood based on the individual's age, race, or other factors
