Question: Ranching: Cattle. You are the foreman of the Bar-S cattle ranch in Colorado. A neighboring ranch has calves for sale, and you are going to buy some calves to add to the Bar-S herd. How much should a healthy calf weigh? Let x be the age of the calf (in weeks), and let y be the weight of the calf (in kilograms). The following information is based on data taken from The Merck Veterinary Manual (a reference used by many ranchers)

x y
1 42
3 50
10 75
16 100
26 150
36 200

Complete parts (a) through (e), given \(\sum{x}\) = 92, \(\sum{y}\) = 617, \(\sum{{{x}^{2}}}\) = 2338, \(\sum{{{y}^{2}}}\) =

82,389, \(\sum{xy}\) = 13,642, and r= 0.998,

(f) The calves you want to buy ate 12 weeks old. What does the least-squares line

predict for a healthy weight?
