The birth weight of elephants at the 85th percentile is 262.16 pounds
<h3>What is the standard deviation?</h3>
Standard deviation is defined as the amount of variation or the deviation of the numbers from each other.
Given that:-
The average birth weight of elephants is 200 pounds     = 200
 = 200
The deviation of 60 pounds.                                               = 60
 = 60 
The birth weight of elephants at the 85th percentile.      z = 85%= 1.036
Now from the formula of z-score:-

Hence the birth weight of elephants at the 85th percentile is 262.16 pounds
