Scores for a common standardized college aptitude test are normally distributed with a mean of 484 and a standard deviation of 99. Randomly selected men are given a Test Preparation Course before taking this test. Assume, for sake of argument, that the preparation course has no effect. If 1 of the men is randomly selected, find the probability that his score is at least 519.8. P(X > 519.8) = Enter your answer as a number accurate to 4 decimal places. If 11 of the men are randomly selected, find the probability that their mean score is at least 519.8. P(M > 519.8) = Enter your answer as a number accurate to 4 decimal places.
