The following Minitab display gives information regarding the relationship between the body weight of a child (in kilograms) and the metabolic rate of the child (in 100 kcal/ 24 hr).

Predictor	Coef	SE Coef	T	P
Constant	0.8624	0.4148	2.06	0.84
Weight	0.41375	0.02978	13.52	0.000
S = 0.517508	R-Sq =94.4%

(a) Write out the least-squares equation.

(b) For each 1 kilogram increase in weight, how much does the metabolic rate of a child increase? (Use 5 decimal places.) (c) What is the value of the correlation coefficientr? (Use 3 decimal places.)
