37) The owner of an electronics shop creates a regression model to help determine the price of a TV based on the size of its screen (in square inches), the quality of its picture (rated on a scale of 1 to 10 by a panel of judges) and the quality of its
sound (also rated on a scale of 1 to 10 by a panel of judges). The regression equation is: Price=256+1.60(ScreenSize)+0.55(PictureQuality) +0.32(SoundQuality) Which is the dependent variable?
