Relative Frequency Cc6470
1. **State the problem:** We are given a two-way table with counts of people who prefer different music genres and shoe types. We need to fill in the total relative frequency table (percentages) based on the counts.
2. **Given data (counts):**
\begin{array}{l|cc|c}
& \text{Hip Hop} & \text{Rock and Roll} & \text{Total} \\
\hline
\text{Basketball Shoes} & 28 & 13 & 41 \\
\text{Crocs} & 6 & 20 & 26 \\
\hline
\text{Total} & 34 & 33 & 67
\end{array}
3. **Formula for relative frequency:**
$$\text{Relative Frequency} = \frac{\text{Count}}{\text{Total number of people}} \times 100\%$$
4. **Calculate each cell's relative frequency:**
- Basketball Shoes, Hip Hop: $\frac{28}{67} \times 100 \approx 41.79\% \approx 42\%$
- Basketball Shoes, Rock and Roll: $\frac{13}{67} \times 100 \approx 19.40\% \approx 19\%$
- Crocs, Hip Hop: $\frac{6}{67} \times 100 \approx 8.96\% \approx 9\%$
- Crocs, Rock and Roll: $\frac{20}{67} \times 100 \approx 29.85\% \approx 30\%$
5. **Calculate row totals (relative frequencies):**
- Basketball Shoes total: $\frac{41}{67} \times 100 \approx 61.19\% \approx 61\%$
- Crocs total: $\frac{26}{67} \times 100 \approx 38.81\% \approx 39\%$
6. **Calculate column totals (relative frequencies):**
- Hip Hop total: $\frac{34}{67} \times 100 \approx 50.75\% \approx 51\%$
- Rock and Roll total: $\frac{33}{67} \times 100 \approx 49.25\% \approx 49\%$
7. **Check grand total:**
- Total relative frequency should be 100% (sum of all counts divided by total counts times 100).
8. **Final relative frequency table (rounded to nearest whole percent):**
\begin{array}{l|cc|c}
& \text{Hip Hop} & \text{Rock and Roll} & \text{Total} \\
\hline
\text{Basketball Shoes} & 42\% & 19\% & 61\% \\
\text{Crocs} & 9\% & 30\% & 39\% \\
\hline
\text{Total} & 51\% & 49\% & 100\%
\end{array}
This table correctly reflects the relative frequencies based on the original counts.
**Note:** The percentages in the user's provided relative frequency table are incorrect (e.g., totals over 100%). Our calculated table is consistent and sums correctly.
