Answer:

The standardized value is -2

Step-by-step explanation:

Given

[tex]mu = 20[/tex] -- mean

[tex]\sigma = 2[/tex] --- standard deviation

Required

Determine the standardized value of X = 16

The standardized value (S) is calculated using:

[tex]S = \frac{X - mu}{\sigma}[/tex]

This gives:

[tex]S = \frac{16 - 20}{2}[/tex]

[tex]S = \frac{- 4}{2}[/tex]

[tex]S = -2[/tex]

The standardized value is -2
