In an evaluation of progress, made to 400 managers, the averageof the scores was 70 and its standard deviation was 8.0, what isthe probability that, if we select a manager at random (among the400 that were evaluated ), did he get 70 or more?
Z = __________________________
1-Z + __________________________
Probability = __________________________ = ____________________%
