A regression of the amount of calories in a serving of breakfast cereal vs. the amount of fat in the cereal gave the following results: Calories = 97.1053 + 9.6525*(grams of fat). Which of the following is FALSE: It is estimated that for every additional gram of fat in the cereal, the number of calories increases by about 9. It is estimated that in cereals with no fat, the total amount of calories is about 97. If a cereal has 2 g of fat, then it is estimated that the total number of calories is about 113. If a cereal has about 145 calories, then this equation indicates that it has about 5 grams of fat. One cereal has 140 calories and 5 g of fat. Its residual is about 5 cal.
