In the united states, birth weights of newborn babies are approximately normally distributed with a mean of μ = 3,500 g and a standard deviation of σ = 500 g. what percent of babies born in the united states are classified as having a low birth weight (< 2,500 g)? explain how you got your answer.

2.775%

Step-by-step explanation:

Given: Mean :

Standard deviation:

The formula to calculate z-score is given by :-

For x= 2,500g

The p-value of z = P(z<-2)=0.02275

In percent,

The percent of babies born in the United States are classified as having a low birth weight (< 2,500 g) = 2.775%
