Tessa's class had a math exam where the grades were between 0 and 10.

N(g) models the number of students whose grade on the exam was g.

What does the statement N(8)>2N(5) mean?

• There are 8 students whose grade was higher than twice the grade of another group of 5 students.

• The number of students whose grade was higher than 5 is greater than the number of students whose grade was 5 or lower.

• The number of students whose grade was 8 is more than twice the number of students whose grade was 5.

• The number of students whose grade was 8 was half as many as the students whose grade was 5.
