use the information given in the table on the right to complete each of the following statements. brenda is 50 inches tall. her z - score is .
Answer
Answer:
$0.5$
Explanation:
Step1: Recall z - score formula
The z - score formula is $z=\frac{x-\mu}{\sigma}$, where $x$ is the data value, $\mu$ is the mean, and $\sigma$ is the standard deviation.
Step2: Identify values
We have $x = 50$ (Brenda's height), $\mu=49$ (mean height), and $\sigma = 2$ (standard deviation).
Step3: Substitute values into formula
$z=\frac{50 - 49}{2}=\frac{1}{2}=0.5$
