Randomly selected men are given a Test Preparation Course before taking this test. Assume, for sake of argument, that the test has no effect. If 1 of the men is randomly selected, find the probability that his score is at least 559.3. P(X > 559.3) = Enter your answer as a number accurate to 4 decimal places. NOTE: Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted. If 7 of the men are randomly selected, find the probability that their mean score is at least 559.3. P(M > 559.3) = Enter your answer as a number accurate to 4 decimal places. NOTE: Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted. If the random sample of 7 men does result in a mean score of 559.3, is there strong evidence to support the claim that the course is actually effective? O No. The probability indicates that is is possible by chance alone to randomly select a group of students with a mean as high as 559.3. Yes. The probability indicates that is is (highly ?) unlikely that by chance, a randomly selected group of students would get a mean as high as 559.3.
