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.
a. Find the equation for the least-squares regression line representing the data.
b. Another woman has a lean body mass of 45 kilograms. What is her predicted metabolic rate?

We have data on the lean body mass and resting metabolic rate
for 10 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.
Body Mass values are: (30,14,42,22,38,40,46,15,56,24)
Metabolic Rates:
(767,623,1260,688,1152,1172,1356,599,1520,808)
