Describe the relationship between the variables. (ii) Graph II shows the same information as Graph I, but also indicates the old and new stadiums. Does Graph II suggest that the rate at which attendance changes as number of games won increases is different in the new stadium compared to the old stadium? Explain your reasoning. Average Attendance (thousands) Average Attendance (thousands)
