calculating z - scores for data related to expenses\nthe monthly expenses for a company are normally distributed with a mean of $5,000 and a standard deviation of $500. if the company had expenses of $5,750 in a particular month, what is the z - score for that months expenses?\nuse the following formula to calculate z - score: $z=\frac{x - mu}{sigma}$ where $x$ is the data point, $mu$ is the mean, and $sigma$ is the standard deviation.\n0.5\n2.0\n1.5\n1.0
Answer
Explanation:
Step1: Identify values
$x = 5750$, $\mu=5000$, $\sigma = 500$
Step2: Substitute into formula
$z=\frac{x - \mu}{\sigma}=\frac{5750 - 5000}{500}$
Step3: Calculate the numerator
$5750-5000 = 750$
Step4: Calculate the z - score
$z=\frac{750}{500}=1.5$
Answer:
1.5
