1. A pork producer is interested in figuring out if weaning weight is associated with a pig's weight at 154 days of age. He collected data on his herd but doesn't know what to do with the data and has asked you to help him since he knows you took this class. Pig # 1 2 3 45 5 69 869 10 Weaning weight (kg) Weight at 154 days (kg) 85 74 6.28 5.12 5.78 4.84 6.10 5.03 6.08 5.31 5.53 6.26 68 60 76 70 85 62 65 80 c. Calculate the correlation coefficient between weaning weight and weight at 154 days of age. What does the value tell the producer? Should he use weaning weight to predict anything about the later weight?
