Question

A private college advertised that last year their freshman students, on average, had a score of 1140 on the college entrance exam. Assuming that average refers to the mean, which of the following claims must be true based on this information? Note: More than one statement could be true. If none of the statements is true, mark the appropriate box. Last year at least one of their freshman students had a score of more than 900 on the exam Next year at least one of their freshman students will have a score of at least 1140 on the exam. Last year fewer than half of their freshman students had a score of 1140 or below on the exam Last year some of their freshman students had a score of exactly 1140 on the exam. Last year all of their freshman students had a score of at least 1140 on the exam O None of the above statements is true.

Explanation / Answer

Since, the mean score is 1140 (>900), there has to be one student at least to score more than 900. Hence, the first statement is true.

Since, no other information is provided, it will not be appropriate to make any other claim (like the number of students that may have scored above or below 1140).

Thus, only the first option is Correct.
