You work for a large dairy farm and are examining the farm's techniques for rearing their Holstein calves. You want to see how large the farm's Holstein calves get as they age. So, you are going to take a random sample of11of the calves and note the age of each calf (denoted byx,inmonths)and their weight (denoted byy,inkg). You will also note the productx(y) of the age and the weight for each of the calves. (These products are written in the row labeled"xy").
