The body mass index (variable BMI) provides an indication of a person's level of body fat as follows: healthy weight, 20-25; overweight, >25-30; obese, greater than 30. Excess body weight is, of course, related to diet, but, in turn, what we eat depends on who we are in terms of culture and our entire life experience. Based on an analysis using mean weight, can you conclude that white people have a healthy weight? Can you conclude that based on mean weight, white people are overweight? You will do the analysis based first on the data from the first interview, create a subset from the data file using daycode = 1, and a second time using data from the second interview, create a subset from the data file using daycode = 2. Note that there are differences in the responses between the first and second interviews.
