Intercept 3.5846 0.4182 8.57 <.001
Cigarettes 0.0641 0.0208 3.08 0.004
  1. Using the regression equation fromquestion 5, how many days would you expect a person to miss from work if he smoked 22 cigarettes daily?
  2. What is the proportion of variance in the number of days missed accounted for by the number of cigarettes smoked (R2)? - look at the Model Fit Measures table
  3. What is the regression equation you would use if you wanted to predict the number of days a person misses from work based on the number of cigarettes smoked?
