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). 1 5 11 16 26 36 n 39 47 73 100 150 200 2x2 = 2y2 = Complete parts (a) through (e), given 2x = 95, By = 609, 2375, 81,559, 2x y = 13,777, and r = 0.997. (a) Make a scatter diagram of the data. (Select the correct graph.) Y (b) Verify the given sums Ex, 2y, 2x2, Eyz, 2x y, and the value of the sample correlation coefficient r. (For each answer, enter a number. Round your value for r to three decimal places.) 2x=:1 (c) Find 1 and V. Then nd the equation of the least-squares line? = a + b x. (For each answer, enter a number. Round your answers for Q and y to two decimal places. Round your answers for a and b to three decimal places.) ~~
