.

Answer 1

To find the average number of students in the class who said they would benefit from tutoring, we can use the information provided about the lower and upper margins.

We know:

• Lower Margin = 10
• Upper Margin = 16

The average can be found by calculating the midpoint of the lower and upper margins:

\[ \text{Average} = \frac{\text{Lower Margin} + \text{Upper Margin}}{2} \]

Substituting in the values:

\[ \text{Average} = \frac{10 + 16}{2} = \frac{26}{2} = 13 \]

Therefore, the average number of students who would benefit from tutoring is 13.
