Chapter 25, Problem 2E
Candy sales A candy maker surveyed chocolate bars available in a local supermarket and found the following least squares regression model:
.
- a) The hand-crafted chocolate she makes has 15 g of fat and 20 g of sugar. How many calories does the model predict for a serving?
- b) In fact, a laboratory test shows that her candy has 227 calories per serving. Find the residual corresponding to this candy. (Be sure to include the units.)
- c) What does that residual say about her candy?
