a newborn who weighs 2,500 g or less has a low birth weight. use the information on the right to find the z - score of a 2,500 g baby. in the united states, birth weights of newborn babies are approximately normally distributed with a mean of $mu = 3,500$ g and a standard deviation of $sigma = 500$ g. $z=\frac{x - mu}{sigma}$

a newborn who weighs 2,500 g or less has a low birth weight. use the information on the right to find the z - score of a 2,500 g baby. in the united states, birth weights of newborn babies are approximately normally distributed with a mean of $mu = 3,500$ g and a standard deviation of $sigma = 500$ g. $z=\frac{x - mu}{sigma}$

Answer

Explanation:

Step1: Identify values

$x = 2500$, $\mu=3500$, $\sigma = 500$

Step2: Substitute into z - score formula

$z=\frac{x - \mu}{\sigma}=\frac{2500 - 3500}{500}$

Step3: Calculate the value

$z=\frac{- 1000}{500}=-2$

Answer:

$-2$
