Given the data from the table, let's fill in the blanks:
First, examining the table:
[tex]\[
\begin{array}{|l|l|r|r|}
\hline
\text{Age Group} & \text{Male} & \text{Female} & \text{Marginal Total} \\
\hline
18 - 24 & 5,640 & 6,432 & 12,072 \\
\hline
25 - 34 & 1,843 & 2,450 & 4,293 \\
\hline
35 + & 1,069 & 2,124 & 3,193 \\
\hline
\text{Total} & 8,552 & 11,006 & 19,558 \\
\hline
\end{array}
\][/tex]
1. The marginal total 4,293 in the table refers to the number of students in the 25-34 age group. Hence, the correct answer is "students in the 25-34 age group".
2. The relative frequency of females in the 35-plus age group compared with the total number of students, expressed as a percentage, is given as 10.860006135596686%. Hence, the correct answer is "10.86%".
So, the completed sentences are:
The marginal total 4,293 is students in the 25-34 age group. 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%.
