The equation of the least-squares regression line is: Calories = 204 + 11 .4*(Fat) The correlation between Calories and Fat is r = .979. Hence, r2 = .958. Finally, the average number of calories in menu items is 663, and the average fat
content in menu items is 40 grams. The least-squares line would predict that a menu item with 40 grams of fat would
have 0 660 calories.
0 100 calories.
0 456 calories. 0 204 calories.
