The slope indicates that for each increase of 1 in wedding cost, the predicted attendance is estimated to increase by a value equal to by. O D. It is not appropriate to interpret the slope because it is outside the range of observed wedding costs. Wedding Cost Attendance 60700 300 Interpret the Y-intercept of the regression equation. Choose the correct answer below. 51000 350 49000 150 O A. It is not appropriate to interpret the Y-intercept because it is outside the range of observed attendances. 43000 200 O B.
