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 som
e 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). x 3 4 11 16 26 36
y 38 51 74 100 150 200
Complete parts (a) through (e), given Σx = 96, Σy = 613, Σx^2 = 2374, Σy^2 = 82,021, Σxy = 13,832, and r = 0.998
(a) Draw a scatter diagram displaying the data
When you have two sets of data, one that represents an independent variable (X) and another that represents a dependent variable (Y) (it is a response of the first variable). A diagram called scatterplot can be generated to present the ordered pairs (X, Y) in the Cartesian plane to see how the two variables are related.
In this case the independent variable (X) is the age variable of the calf and the dependent variable (Y) is the weight of the calf.
