Hello, please answer all parts if possible. if not, please answer c, e and f, thank you. 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).х| 1y 3947Complete parts (a) through (e), given Ex = 95, Ey = 609, Ex? = 2375, Ey = 81,559, Ex y = 13,777, and r* 0.997.(a) Make a scatter diagram of the data.
