You're trying to see if there is wage discrimination against group A relative to group B. Among the covariates you are using are x₁ and x2. You find that you have no observations of group A with x₁ <7 and no observations of group B with x₁ >14. You also have no observations of group A with x2 >105 and no observations of group B with x2 < 87. To get the data set you will work with, you should Choose one: 1. Keep only observations with x1 between 7 and 14 inclusive, and x2 between 87 and 105 inclusive. 2.Keep only observations with x1 between 7 and 14 inclusive, or observations of x2 between 87 and 105 inclusive 3.Use the entire data set you have. 4. You really can't do anything at all with ths data set
