Given that z is a standard normal random variable,
the area to the left of z is .2119.
The area to the left of z is given and we need to find out the z-score
To find z we use z-score table
z- score table is attached below.
We look at the z- score that has value 0.2119
From the table we can see that 0.2119 has z-score -0.80
the area to the left of -0.80 is .2119.
