Answer 1

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:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

Putting all the values, we have

$z_{score} = \displaystyle\frac{1370 - 810}{235} = 2.383$

John's standard z-score is 2.383
