A sample of 80 high school drama club and art club students were surveyed to choose a favorite free-time activity: playing computer games, listening to music, or watching movies/TV. [tex]$50\%$[/tex] of the sample is drama club students. From the sample, it is found that [tex]$25\%$[/tex] were drama club students who prefer listening to music and [tex]$20\%$[/tex] were drama club students who prefer watching movies/TV. [tex]$18.75\%$[/tex] were art club students who prefer playing computer games, while [tex]$15\%$[/tex] were art club students who prefer listening to music. [tex]$40\%$[/tex] of the students surveyed chose listening to music.

Which of the following is a correct two-way relative frequency table for the data?

Answer :

Let's solve the problem step-by-step by analyzing the given information and filling out the two-way relative frequency table.

1. Total Number of Students
- Total students: 80

2. Proportions of Students
- Drama club students: 50% of 80 = 40 students
- Art club students: 80 - 40 = 40 students

3. Drama Club Preferences
- 25% of drama students prefer listening to music: [tex]\( 0.25 \times 40 = 10 \)[/tex] students
- 20% of drama students prefer watching movies/TV: [tex]\( 0.20 \times 40 = 8 \)[/tex] students
- Remaining drama students prefer playing computer games: [tex]\( 40 - 10 - 8 = 22 \)[/tex] students

4. Art Club Preferences
- 18.75% of art students prefer playing computer games: [tex]\( 0.1875 \times 40 = 7.5 \)[/tex] students
- 15% of art students prefer listening to music: [tex]\( 0.15 \times 40 = 6 \)[/tex] students
- Remaining art students prefer watching movies/TV: [tex]\( 40 - 7.5 - 6 = 26.5 \)[/tex] students

5. Summarizing the Totals
- Total students preferring playing computer games: [tex]\( 22 + 7.5 = 29.5 \)[/tex]
- Total students preferring listening to music: [tex]\( 10 + 6 = 16 \)[/tex]
- Total students preferring watching movies/TV: [tex]\( 8 + 26.5 = 34.5 \)[/tex]

6. Relative Frequency Table Options
○ Option 1:
[tex]\[ \begin{tabular}{|c|l|l|l|l|} \hline & Drama Club and Art Club Leisure Time Activity Preferences & \\ \hline & Playing Computer Games & Listening to Music & Watching Movies/TV & Row Totals \\ \hline Drama Club Students & 22 \text{ (27.5\%)} & 10 \text{ (12.5\%) } & 8 \text{ (10\%) } & 40 \text{ (50\%) } \\ \hline Art Club Students & 7.5 \text{ (9.4\%)} & 6 \text{ (7.5\%) } & 26.5 \text{ (33.1\%) } & 40 \text{ (50\%) } \\ \hline Column Totals & 29.5 \text{ (37\%)} & 16 \text{ (20\%)} & 34.5 \text{ (43.1\%)} & 80 \text{ (100\%)} \\ \hline \end{tabular} \][/tex]

By examining the different options provided, the correct table needs to match these totals and proportions accurately. Given that our calculated values align with the problem's stated relative frequencies used to categorize the survey sample, we can confidently confirm which table option corresponds with these findings.

Upon reviewing the provided options, we find that the most accurate representation is the one given as:
```

\begin{tabular}{|c|l|l|l|l|}
\hline & & Drama Club and Art Club Leisure Time Activity Preferences & \\
\hline & Playing Computer Games & Listening to Music & Watching Movies/TV & Row Totals \\
\hline Drama Club Students & 22 & 10 & 8 & 40 \\
\hline Art Club Students & 7.5 & 6 & 26.5 & 40 \\
\hline Column Totals & 29.5 & 16 & 34.5 & 80 \\
\hline
\end{tabular}
```

This is the table that accurately reflects our calculated totals and relative frequencies.
