A nutritionist was interested in developing a model that describes the relation between the amount of fat [in grams} in cheeseburgers at fastfood restaurants and the number of calories. She obtains the accompanying data from the Web sites of the companies, which is also displayed in the accompanying scatter diagram. It has been determined that the linear correlation coefficient is H.944 and that a linear relation exists between fat content and calories in the fastfood restaurant sandwiches. Complete parts {a} through {e} belowt Clicl: here to iriewr the sandwich data. Clicl: here to iriewr the scatter diagram. {a} Find the leastsquares regression line treating fat content as the explanatory variable. rowan) [Round to trim decimal places as needed} \f(c) Interpret the slope and y-intercept, if appropriate. Interpret the slope, if appropriate. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. For each additional gram of fat in a fast-food sandwich, the sandwich is expected to have more calorie(s). (Round to two decimal places as needed.) O B. For each additional calorie in a fast-food sandwich, the sandwich is expected to have more gram(s) of fat. (Round to two decimal places as needed.) O C. Each additional calorie in a fast-food sandwich gives the sandwich additional gram(s) of fat. (Round to two decimal places as needed.) O D. Each additional gram of fat in a fast-food sandwich gives the sandwich additional calorie(s). (Round to two decimal places as needed.) O E. It is not appropriate to provide an interpretation of the slope.Interpret the vintercept, if appropriate.

D D- Fastfood sandwiches with D calorie[s) have D gramEs) hr fat. [Round to two decimal places as needed.) Ci E. It is not appropriate to provide an interpretation of the vintercept. (d) Predict the number of calories in a sandwich that has 30 grams of fat. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. calorie(s) (Round to one decimal place as needed.) O B. It is not appropriate to provide such a prediction.(e) A cheeseburger from a restaurant that was not included in the nutritionist's data has 700 calories and 42 grams of fat. Is the number of calories for this sandwich above or below average among all sandwiches with 42 grams of fat? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The number of calories for this sandwich is below the average among all sandwiches with 42 grams of fat, which is according to the linear model. (Round to one decimal place as needed.) O B. The number of calories for this sandwich is above the average among all sandwiches with 42 grams of fat, which is according to the linear model. (Round to one decimal place as needed.) O C. It is not appropriate to provide such a comparison
