Scores for a common standardized college aptitude test are normally distributed with a mean of 502 and a standard deviation of 102. Randomly selected students are given a Test Prepartion Course before taking this test. Assume, for sake of argument, that the course has no effect. If 1 of the students is randomly selected, find the probability that their score is at least 556.7. P(X > 556.7) = Enter your answer as a number accurate to 4 decimal places. If 5 of the students are randomly selected, find the probability that their mean score is at least 556.7. P(X > 556.7) = Enter your answer as a number accurate to 4 decimal places
