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. -2 complete what is the z - score of a newborn who weighs 4,000 g? done 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
Given $\mu = 3500$, $\sigma=500$, $x = 4000$.
Step2: Apply z - score formula
$z=\frac{x - \mu}{\sigma}=\frac{4000 - 3500}{500}$
Step3: Calculate result
$\frac{4000 - 3500}{500}=\frac{500}{500}=1$
