Q. Tessa's class had a math exam where the grades were between

0

and

10

.

\newline

N(g)

models the number of students whose grade on the exam was

g

.

\newline

What does the statement

\newline

N(8) > 2 \cdot N(5)

mean?

\newline

Choose

1

answer:

\newline

(A) The number of students whose grade was higher than

5

is greater than the number of students whose grade was

5

or lower.

\newline

(B) The number of students whose grade was

8

is more than twice the number of students whose grade was

5

.

\newline

(C) There are

8

students whose grade was higher than twice the grade of another group of

5

students.

Understanding the problem: Understanding the problem: The statement $N(8) > 2 \times N(5)$ means that the number of students who scored an $8$ on the exam is greater than twice the number of students who scored a $5$ .
Analyzing answer choices: Analyzing the answer choices: $\newline$ (A) Incorrect because it talks about students scoring higher than $5$ compared to those scoring $5$ or lower, which isn't relevant to our specific comparison of scores $8$ and $5$ . $\newline$ (B) Correct as it directly matches our understanding of the statement $N(8) > 2\cdot N(5)$ . $\newline$ (C) Incorrect because it misinterprets the statement as comparing a group of $8$ students to a calculation involving another group, which is not what $N(8) > 2\cdot N(5)$ indicates.
