A candy maker surveyed chocolate bars available in a local supermarket and found the least squares regression model shown below. Use the model to answer parts a through c below. Calories = 28.9+12.65Fat(g) +2.41Sugar(g) a) The hand-crafted chocolate she makes has 15g of fat and 20g of sugar. How many calories does the model predict for a serving? calories (Type an integer or a decimal. Do not round.) b) In fact, a laboratory test shows that her candy has 248 calories per serving. Find the residual corresponding to this candy. calories (Type an integer or a decimal. Do not round.) c) What does that residual say about her candy? Choose the correct choice below and fill in the answer box within your choice. (Type an integer or a decimal. Do not round.) OA. Her candy has OB. Her candy has more calories than might be expected from the model. fewer calories than might be expected from the model.
