1. In the population model: cigsi = βo + β1educi + ui a) Interpret the coefficient β1. β1 represents the slope of the regression line and is the change in cigs associated with a unit change in educ. So for one unit increase of educ there will be β1 units increase/decrease (depending on the sign of β1) in the cigs. b) Can you predict the sign of β1 (without doing any estimation)? Explain. The sign of β1 would most probably be minus looking at the information from the surveys in
