The average birth weight of elephants is 200 pounds. Assume that the distribution of birth weights is Normal with a standard dev
zhenek [66]

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    \mu = 200

The deviation of 60 pounds.                                              \sigma = 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

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