If 1 of the men is randomly selected, find the probability that his score is at least 518.6. P(x > 518.6) = Incorrect Enter your answer as a number accurate to 4 decimal places. If 13 of the men are randomly selected, find the probability that their mean score is at least 518.6. P(x-bar > 518.6) = Incorrect Enter your answer as a number accurate to 4 decimal places. Assume that any probability less than 5% is sufficient evidence to conclude that the preparation course does help men do better. If the random sample of 13 men does result in a mean score of 518.6, is there strong evidence to support the claim that the course is actually effective? No. The probability indicates that it is too possible by chance alone to randomly select a group of students with a mean as high as 518.6. Yes. The probability indicates that it is (highly ?) unlikely that by chance, a randomly selected group of students would get a mean as high as 518.6.
