Question

There is an increasing interest in healthier lifestyles, especially among the younger population. This is exhibited in the increased interest in exercise and a variety of emphases on eating foods that contribute to a higher-quality diet. You have been asked to determine if people who are physically active (variable activity level = 2 or 3) have healthier diets compared to those who are not (variable activity level = 1). Determine if there is strong evidence for your conclusion. You will do the analysis based first on the data from the first interview and create subsets of the data file using daycode = 1, and then a second time using data from the second interview, creating subsets of the data file using daycode = 2.
