Un puntaje z de 1,067 corresponde a un área de 14,231
p(z<1,067)=14,231
La probabilidad acumulativa de que z<1,067 sea 1423100%

2. Find the cumulative probability for the z-scores values greater than 1.067

To find the cumulative probability of the values greater than 1,067, we need to subtract the cumulative probability of the values less than 1,067 from the total probability under the curve, which is equal to 1:

114,231=14230
p(z>1,067)=14230
The cumulative probability of z>1,067 is 1423000%
