answer the questions

A magazine used the summated rating of 10 restaurants to predict the cost of a restaurant meal. For that data, SSR = 133, 182.79 and SST = 142,080.83. Complete parts (a) through (c). a. Determine the coefficient of determination, r, and interpret its meaning. 12 =(Round to four decimal places as needed.) Interpret the meaning of r2. It means that % of the variation in the cost of a meal be explained by the variation in summated ratings. (Round to two decimal places as needed.) b. Determine the standard error of the estimate. Syx =(Round to four decimal places as needed.) c. How useful do you think this regression model is for predicting the cost of a meal? A. It is very useful for predicting the cost of a meal because the coefficient of determination is close to 1. The standard error of the estimate does not indicate whether a regression model is useful. O B. It is not very useful for predicting the cost of a meal because the coefficient of determination is close to 0 and the standard error of the estimate is fairly large. O C. It is very useful for predicting the cost of a meal because the coefficient of determination is close to 1 and the standard error of the estimate is fairly small. O D. It is not very useful for predicting the cost of a meal because although the coefficient of determination is close to 1, the standard error of the estimate is fairly small
