1. Find the cumulative probability of the z-scores values up to $- 26.2$

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 $- 26, 2$ is $0$ .
$p (x < - 26, 2) = 0$
The cumulative probability that $x < - 26, 2$ is $0 %$

2. Find the cumulative probability of the z-scores values up to $- 33.8$

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 $- 33, 8$ es $0$ .
$p (x < - 33, 8) = 0$
La probabilidad acumulativa de que $x < - 33, 8$ sea $0 %$

3. Calculate the cumulative probability between -26.2 and -33.8

To find the cumulative probability of the area between the two z-scores, subtract the smaller cumulative probability (everything to the left of $- 33, 8$ ) from the larger cumulative probability (everything to the left of $- 26, 2$ ):

$0 - 0 = 0$
$p (- 33, 8 < x < - 26, 2) = 0$
The cumulative probability that $- 33, 8 < x < - 26, 2$ is $0 %$
