You can put this solution on YOUR website! One Thousand skilled workers were given an examination to determine how much they know about their job. If the scores are normally distributed and the score of one worker measured in z score is 0.8, how many of the workers who took the examination scored higher than or equal to this particular worker?
-------------
P(z > 0.8) = normalcdf(0.8,100) = 0.2119
-------
Ans: x = 0.2119*1000 = 212 (# of workers who scored higher)
