Un puntaje z de 1,212 corresponde a un área de 11,314
p(z<1,212)=11,314
La probabilidad acumulativa de que z<1,212 sea 1131400%

2. Find the cumulative probability for the z-scores values greater than 1.212

To find the cumulative probability of the values greater than 1,212, we need to subtract the cumulative probability of the values less than 1,212 from the total probability under the curve, which is equal to 1:

111,314=11313
p(z>1,212)=11313
The cumulative probability of z>1,212 is 1131300%
