A number of nutritionists have argued that fastfood restaurants have a negative effect on nutrition quality. In this exercise you are asked to determine if there is evidence to conclude that increasing the number of meals at fast-food restaurants will have a negative effect on diet quality. In addition, you are asked to determine the effect of eating in fast-food restaurants has on the daily cost of food. You will do the analysis based first on the data from the first interview, creating subsets of the data file using daycode = 1, and a second time using data from the second interview, creating subsets of the data file using daycode = 2.
