. The relative frequency of females in the 35-plus age group compared with the total number of students, expressed as a percentage, is ___
The marginal total 4,293 represents the total number of students in the 25-34 age group.
To find the relative frequency of females in the 35-plus age group compared with the total number of students, we divide the number of females in the 35+ age group (2,124) by the total number of students (19,558) and then multiply by 100 to express it as a percentage.
Relative frequency of females in the 35+ age group = (2,124 / 19,558) * 100 = 10.86%
Therefore, the relative frequency of females in the 35-plus age group compared with the total number of students, expressed as a percentage, is 10.86%.
