A magazine publishes restaurant ratings for various locations around the world. The magazine rates the restaurants for food, decor, service, and the cost per person. Develop a regression model to predict the cost per person, 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 (a) through (e) below. a. Construct a scatter plot. Choose the correct graph below. O A. A Cost (S) 90- Rating 90 B. A Cost (S) 90- 1 Rating 90 C. A Cost (S) 90- Rating 90 Q b. Assuming a linear relationship, use the least-squares method to compute the regression coefficients bo and b₁. bo=and b₁ = (Round to two decimal places as needed) D. A Cost (S) 90- 0- Rating 90
