Market researchers were interested in the relationship between the price of bobbleheads and the demand of
bobbleheads. Information was collected from a survey and was used to obtain the regression equation ý = -0.277X +
50.455, where x represents the price of a bobblehead (measured in dollars) and ŷ is the predicted demand of
bobbleheads in units). Which statement best describes the meaning of the slope of the regression line?
* For each increase in demand by 1 unit, the predicted price decreases by $0.227.
For each increase in demand by 1 unit, the predicted price decreases by $50.455.
For each increase in price by $1, the predicted demand decreases by 0.227 units.
For each increase in price by $1, the predicted demand decreases by 50.455 units.
