Answer: The z score that corresponds to the value x=22 is 0.4 .

Step-by-step explanation:

Given : A normal distribution has a mean 20 and standard deviation 5.

i.e. \mu=20

\sigma=5

Let x be the random selected variable.

We know that to find the z-score corresponds to the value x is given by :-

z=\dfrac{x-\mu}{\sigma}

For x = 22, we have

z=\dfrac{22-20}{5}=\dfrac{2}{5}\\\\\Rightarrow\ z=0.4

Hence, the z score that corresponds to the value x=22 is 0.4

x=25.36\times 1.45

x=36.772

Therefore, x=36.772
