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. what is the z - score of a newborn who weighs 4,000 g? 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. what is the z - score of a newborn who weighs 4,000 g? 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

$x = 4000$, $\mu=3500$, $\sigma = 500$

Step2: Apply z - score formula

$z=\frac{x - \mu}{\sigma}=\frac{4000 - 3500}{500}$

Step3: Calculate the result

$\frac{4000 - 3500}{500}=\frac{500}{500}=1$

Answer:

$1$
