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. He collects the
following data:
Number of Cigarettes Smoked per Day
