Answer:

Z=-1.2

Explanation:

From the question we are told that:

Normal distribution
x=35

Mean of normal distribution
$\=x=65$

Standard normal distribution deviation
$\sigma= 25$

Generally the equation for standardized value is mathematically given by

$Z=(x-\=x)/(\sigma)$

Z=(35-65)/(25)

Z=-1.2

Therefore the standardized value of x is

Z=-1.2
