Answer:
its the first answer choice!
Step-by-step explanation:
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
The deviation of 60 pounds.
= 60
The birth weight of elephants at the 85th percentile. z = 85%= 1.036
Now from the formula of z-score:-
![z=\dfrac{x-\mu}{\sigma}\\\\\\z=\dfrac{x-200}{60}\\\\\\1.036\times 60=x-200\\\\\\x=\ \ 262.16\ pounds](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%5C%5C%5C%5C%5C%5Cz%3D%5Cdfrac%7Bx-200%7D%7B60%7D%5C%5C%5C%5C%5C%5C1.036%5Ctimes%2060%3Dx-200%5C%5C%5C%5C%5C%5Cx%3D%5C%20%5C%20262.16%5C%20pounds)
Hence the birth weight of elephants at the 85th percentile is 262.16 pounds
