Question 1102156: The birth weight of a certain species of dolphins is normally distributed with a mean weight of 47.4 pounds and a variance of 6.25. We would expect approximately 95% of newborn dolphins of that species to weigh between ______ pounds. Answer by Lightning_Fast(78) (Show Source):
You can put this solution on YOUR website! 47.4 is the mean weight.
The variance is the standard deviation squared, so is the standard deviation.
Now, 95% of newborn dolphins should weigh within 2 standard deviations of the mean.
So is they smallest the dolphin should weight
and is the maximum value the dolphin should weight.
