Question

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	40.8	39.6	36.4	43	42.2	36	44.8	44.3	48.3	39.2	44.6	38.4
Rate	920	1180	980	1120	1340	1150	1530	1060	1160	1350	1210	1400

Find the least-squares regression line for predicting metabolic rate from body mass.
