National health and nutrition examination survey

Reference no: EM131109973

The Third National Health and Nutrition Examination Survey (NHANES III, 1988-1994) was conducted by the National Center for Health Statistics, Centers for Disease Control and Prevention. This survey was designed to obtain nationally representative information on the health and nutritional status of the population of the United States. Specifically, it contains various body measurements and information on other health-related variables for the respondents. We consider here a portion of this data set for those 13,267 NHANES III participants who were at least 21 years old and not pregnant at the time they completed their surveys.

Body mass index (BMI), which is commonly used to classify an adult's weight status, will be the variable of interest in this problem. It is calculated as the ratio of weight (kg) to height squared (m²). Table 15.2 in the NSM Third Edition R package (sample subset included here) provides the following NHANES III data for each of these 13,267 subjects: Gender, Age, BMI, Arm Circumference (Arm Cir), Buttocks Circumference (Buttocks Cir), and Thigh Circumference (Thigh Cir).

Select an SRS of 25 subjects from this population of NHANES III participants represented in Table 15.2. Be explicit about how you choose the individuals to include in your SRS.
