Suppose we fit a regression line to predict the number of incidents of lung cancer per 10,000 people from the number of cigarettes smoked in a year. For a particular year, we predict the incidence of lung cancer to be 7.9 per 10,000 people, and the residual for this year is -0.42. Did we overestimate or underestimate the incidence of lung cancer?
