Birth weights are normally distributed with a meanof 3421 g and a standard deviationof 496 g. If a hospital plans to set up special observation conditions for the lightest 3% of babies, what weight is used for the cut-off seperating the lightest 3% from the others?
The cut-off weight that separates the lightest 3% of babies from the others is _________g. (round to the nearest gram as needed)
Solution: Denote by X the weight of a new born baby. Then x follows a normal distribution with a mean of 3421 g and a standard deviation of 496 …
This solution is comprised of a detailed solution of finding a value using the standard normal distribution.
