1. Find the cumulative probability of the z-scores values up to $- 210$

More than $99, 9 %$ of the time, data with a standard normal distribution lies within plus or minus $3, 9$ standard deviations of the mean.

The cumulative probability of the values up to $- 210$ is $0$ .
$p (y < - 210) = 0$
The cumulative probability that $y < - 210$ is $0 %$

2. Find the cumulative probability for the z-scores values greater than $- 210$

La probabilidad acumulativa de los valores mayores que $- 210$ es $1$ .

$p (y > - 210) = 1$
La probabilidad acumulativa de $y > - 210$ es $100 %$
