Un puntaje z de 0,702 corresponde a un área de 24,196
p(x<0,702)=24,196
La probabilidad acumulativa de que x<0,702 sea 2419600%

2. Find the cumulative probability for the z-scores values greater than 0.702

To find the cumulative probability of the values greater than 0,702, we need to subtract the cumulative probability of the values less than 0,702 from the total probability under the curve, which is equal to 1:

124,196=24195
p(x>0,702)=24195
The cumulative probability of x>0,702 is 2419500%
