Question Analysis
This question tests the student's ability to calculate the new marginal relative frequency after an increase in the total number of students. The new marginal relative frequency is the ratio of the updated number of 11th-grade students to the new total number of students.

Key Concept Explanation
Marginal Relative Frequency: It is the ratio of the number of students in a single variable category (e.g., 11th-grade students) to the total number of students in the population.
