Immigration has become an important topic in American politics. Some immigrants came to the United States to do jobs that Americans do not want to do. Many of these immigrants have little formal education. Other immigrants came to the United States with work permits. Many of these are highly educated.

b. Are the required conditions satisfied? Explain.
c. If the required conditions are not satisfied what other technique can be used to answer the question?
Consumer behavior while waiting in line. The Journal of Consumer Research (November 2003) published an analysis of consumer behavior while waiting in a queue. A sample of college students were asked to imagine that they were waiting in line at a post office to mail a package and that the estimated waiting time is 10 minutes or less. After a 10-minute wait, students were asked about their level of negative feelings (annoyed, anxious) on a scale of 1 (strongly disagree) to 9 (strongly agree). Before responding, however, the students were informed about how many people were ahead of them and behind them in the line. The researchers used regression to relate the negative feelings score () to the number ahead in line () and the number behind in line ().
a. The researchers fit an interaction model to the data. Write the hypothesized equation of this model.
