13 Homework Question 1, 13.2.5-T HW Score: 21.11%, 3.17 of 15 points Part 4 of 5 Points: 0.17 of 1 Save 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. Click the icon to view the table of summated ratings and cost per person. 0 90 90 to 90 Summated Ratings and Cost Per Person Rating Rating Rating b. Assuming a linear relationship, use the least-squares method to compute the regression coefficients bo and by. Summated Rating Cost ($ per person) bo = - 29.49 and by = 1.25 (Round to two decimal places as needed.) c. Interpret the meaning of the Y-intercept, bo, and the slope, by . Choose the correct answer below. O A. The Y-intercept, bo, implies that if the summated rating of a restaurant is zero, the cost per person is bo, in dollar O B. The Y-intercept, bo, implies that if the summated rating of a restaurant is zero, the cost per meal is equal to bo, in per person, the summated rating is expected to increase by by . C. A practical interpretation of the Y-intercept bo is not meaningful because no operating restaurant is likely to have summated rating, the cost per person is expected to increase by the value of b, , in dollars. O D. The Y-intercept, bo, implies that if the summated rating of a restaurant is zero, the cost per meal is equal to bo, in rating, the cost per person is expected to decrease by by , in dollars. d. Predict the mean cost per person for a restaurant with a summated rating of 40. Y, = $ per person (Round to the nearest cent as needed.) ew an example Get more help
