Answer: 2.4515

Step-by-step explanation:

Given : The mean monthly rent of students at Oxnard University is \mu=\$890 with a standard deviation of \sigma=\$206

Using the formula , z=\dfrac{x-\mu}{\sigma}, we have the  standardized z-value for x= 1395 as

z=\dfrac{1395-890}{206}=2.45145631068\approx2.4515\ \text{ [To the nearest four decimal places.]}

Hence, the standardized z-score = 2.4515
