Answer: weight of elephant has smaller percent error.
Step-by-step explanation:
Percent error = ![\dfrac{|\text{estimated value -actual value}|}{\text{actual value}}]\times100](https://tex.z-dn.net/?f=%5Cdfrac%7B%7C%5Ctext%7Bestimated%20value%20-actual%20value%7D%7C%7D%7B%5Ctext%7Bactual%20value%7D%7D%5D%5Ctimes100)
Estimated weight of elephant = 10,000 pounds
Actual weight of elephant = 12,400 pounds
Percent error of weight = 
Estimated weight of hippopotamus = 2,500 pounds
Actual weight of hippopotamus = 3,600 pounds
Percent error of weight = 
Since 19.35 < 30.55
hence, weight of elephant has smaller percent error.
