The mean monthly rent of students at Oxnard university is 970 with a standard deviation of 204. John`s rent is 1390. What is his standardized z-score? Is john`s rent an outlier? How high would the rent have to be to qualify as an outlier

Standardized z score = 2.06

His house rent is not an outlier

Step-by-step explanation:

The mean monthly rent of students at Oxnard university is 970 with a standard deviation of 204. John`s rent is 1390. What is his standardized z-score? Is john`s rent an outlier? How high would the rent have to be to qualify as an outlier

We solve using z score formula

= z = (x-μ)/σ, where

x is the raw score = 1390

μ is the population mean = 970

σ is the population standard deviation = 204

His z score is calculated as:

z = 1390 - 970/204

z = 2.06

No his house rent is not an outlier
