Answer:
1)
The total number of students in the 25-34 age group.
2)
10.9%
Step-by-step explanation:
We are given a table as follows:
Age Group Male Female Marginal Total
18–24 5,640 6,432 12,072
25–34 1,843 2,450 4,293
35+ 1 ,069 2,124 3,193
Total 8,552 11,006 19,558
We know that the marginal total is the total of all the entries along the row i.e. it is the total number of students of the two genders in the given age group.
Hence,The marginal total 4,293 is 1. the total number of students in the 25-34 age group.
Also, The relative frequency of females in the 35-plus age group compared with the total number of students, expressed as a percentage, is 2. 10.9%.
( Since, the relative frequency is calculated as:
(Number of females in 35+ age group/Total number of students)×100
= (2124/19558)×100
=10.9% )
