You are interested in using linear regression to test whether the number of minutes spent under a sunlamp help improve symptoms of Seasonal Affective Disorder (SAD). From a sample of 100 residents of the Seattle, Washington area, you estimate linear regression model with SAD as the dependent variable (based on a rating system where the rating increases as mood improves) and SUNLAMP as the independent variable. You estimate the slope to equal 1.5. Choose the best interpretation of this evidence. O For every minute spent under the sun lamp, the SAD rating increases by 1.5 units. O For every minute spent under the sun lamp, the SAD rating decreases by 1.5 units. O For every minute spent under the sun lamp, the SAD rating does not change. O For every 1.5 unit increase in the SAD rating, the number of minutes spent under the sunlamp increase by 1.5 minutes.
