Extracted text: Scores for a common standardized college aptitude test are normally distributed with a mean of 516 and a standard deviation of 110. Randomly selected men are given a Test Prepartion Course before taking this test. Assume, for sake of argument, that the test has no effect. 10 If 1 of the men is randomly selected, find the probability that his score is at least 553.4.

C2 2 2 If the random sample of 17 men does result in a mean score of 553.4, is there strong evidence to 2 21 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 553.4. 3 3 O 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 553.4. 3 3. 3 1222222N 222 233 33 3.
