A magazine publishes restaurant ratings for various locations around the world. The magazine rates the restaurants forfood, decor, service, and the cost per person. Develop a regression model to predict the cost perperson, based on a variable that represents the sum of the three ratings. The magazine has compiled the accompanying table of this summated ratings variable and the cost per person for 25 restaurants in a major city. Complete parts(b and c) below.
