Answer:
$299
Step-by-step explanation:
Rent+standard deviation 890+206= $1,096
John's rent: $1,395
Z-score: 1395 - 1096=$299
Answer: 2.4515
Step-by-step explanation:
Given : The mean monthly rent of students at Oxnard University is [tex]\mu=\$890[/tex] with a standard deviation of [tex]\sigma=\$206[/tex]
Using the formula , [tex]z=\dfrac{x-\mu}{\sigma}[/tex], we have the standardized z-value for x= 1395 as
[tex]z=\dfrac{1395-890}{206}=2.45145631068\approx2.4515\ \text{ [To the nearest four decimal places.]}[/tex]
Hence, the standardized z-score = 2.4515
