We have data on the lean body mass and resting metabolic rate for 12 women who are subjects in a study of dieting. Lean body mass, given in kilograms, is a person's weight leaving out all fat. Metabolic rate, in calories burned per 24 hours, is the rate at which the body consumes energy.
| Mass | 39.9 | 39.5 | 54.2 | 40.1 | 44 | 43.6 | 50.9 | 39.9 | 40.3 | 52 | 52.4 | 49.8 |
| Rate | 1300 | 1450 | 1270 | 1410 | 1310 | 1410 | 1300 | 1270 | 1260 | 1510 | 1160 | 1410 |
Find the least-squares regression line for predicting metabolic rate from body mass.
