1. Find the cumulative probability of the z-scores values up to $- 9.629$

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 $- 9, 629$ is $0$ .
$p (x < - 9, 629) = 0$
The cumulative probability that $x < - 9, 629$ is $0 %$

2. Find the cumulative probability of the z-scores values up to $- 9.63$

Más del $99, 9 %$ del tiempo, los datos con una distribución normal estándar se encuentran dentro de más o menos $3, 9$ desviaciones estándar de la media.

La probabilidad acumulativa de los valores hasta $- 9, 63$ es $0$ .
$p (x < - 9, 63) = 0$
La probabilidad acumulativa de que $x < - 9, 63$ sea $0 %$

3. Calculate the cumulative probability between -9.629 and -9.63

To find the cumulative probability of the area between the two z-scores, subtract the smaller cumulative probability (everything to the left of $- 9, 63$ ) from the larger cumulative probability (everything to the left of $- 9, 629$ ):

$0 - 0 = 0$
$p (- 9, 63 < x < - 9, 629) = 0$
The cumulative probability that $- 9, 63 < x < - 9, 629$ is $0 %$
