For a sample of 10 individuals, a researcher calculates residuals for the relationship between “number of delinquent friends” and “number of prior arrests” and finds that the positive residuals = 125. The researcher then collects a second sample of 10 individuals and calculates the residuals on the same two variables and discovers the sum of the positive residuals = 75. What can you conclude about the strength of the relationship between “number of delinquent peers” and “number of prior arrests” across these two random samples? How are they similar/different?

A researcher investigates whether there is a relationship between the number of cigarettes a person smokes and whether the person wears a seat belt when driving. His thinking is that people who smoke more are less concerned about their health and safety and therefore may be less inclined to wear seat belts.
