This exam goes through with a single case. As you solve more questions, more information will be given in blue text. James took an exam last week. Although he expected a high score, his score 72 was below his expectation. So he wanted to know whether his score is above the ayerage score of all students in the class. He asked all 35 students in his class about exam scores and received answers from 17 students. The average of the 17 scores was 67 . So he thought he did a good job because his score was greater than the average score he obtained. Can James definitely trust that his score 72 is higher than the class "average of all" students? Yes, because 72 is greater than 67 Yes, because 72 is quite different from 67. Yes, because James expected that his score is greater. No
