In the feeder pig example, what was the average final weight of the slaughter hogs?

• A. 180 lb
• B. 200 lb
• C. 210 lb
• D. 230 lb

Answer: (C)

Average final weight is the arithmetic mean of all slaughter weights in the batch. You sum each hog’s final weight at slaughter and divide by how many hogs were slaughtered. In the feeder pig example, the final weights listed for the slaughter hogs center around 210 pounds, so when you divide the total by the number of hogs, the result comes out to about 210 pounds. That’s why 210 pounds is the correct average. If the weights had been generally lighter, the average would drop toward 200; if heavier, it would rise toward 230, but the data given produce a mean of 210.
