Answer:
John's standard z-score is 2.383
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = $810
John's rent = $1370
Population standard deviation, σ = $235
Formula:
[tex]z_{score} = \displaystyle\frac{x-\mu}{\sigma}[/tex]
Putting all the values, we have
[tex]z_{score} = \displaystyle\frac{1370 - 810}{235} = 2.383[/tex]
John's standard z-score is 2.383
