The relative frequency of the percentage of seventh grade who prefer mountains can be calculated by dividing the number of seventh-grade students who prefer mountains (40) by the total number of students (310), then converting the result to a percentage.
Relative frequency = (Number of 7th grade students who prefer mountains / Total number of students) * 100
Relative frequency = (40 / 310) * 100
Relative frequency = 0.129 * 100
Relative frequency = 12.9%
Therefore, the relative frequency of the percentage of seventh grade students who prefer mountains is 12.9%. This can be rounded to the nearest tenth, which would be 13.0%.
Use the table to answer the question.
