Final answer:
The statement n(8)>2 · n(5) means that more than twice as many students received a grade of 8 compared to those who received a grade of 5 on the math exam.
Step-by-step explanation:
The statement n(8)>2 · n(5) means that the function n(g), which represents the number of students scoring a grade g, indicates there are more than twice as many students who scored an 8 on the exam compared to those who scored a 5. This is a comparison of the quantities of students for two different grades on the math exam.
In terms of interpreting data, this could imply that the exam had content that students found to be of moderate difficulty (with more students doing well on it, i.e., scoring an 8) compared to the content that might have been related to the score of 5. If one were analyzing the outcomes or effectiveness of studying methods, this comparison could be significant. It may also be relevant for educators who are evaluating the distribution of grades to adjust teaching strategies or exam difficulties.
