Un puntaje z de 2,084 corresponde a un área de 1,876
p(z<2,084)=1,876
La probabilidad acumulativa de que z<2,084 sea 187600%

2. Find the cumulative probability for the z-scores values greater than 2.084

To find the cumulative probability of the values greater than 2,084, we need to subtract the cumulative probability of the values less than 2,084 from the total probability under the curve, which is equal to 1:

11,876=1875
p(z>2,084)=1875
The cumulative probability of z>2,084 is 187500%
