To find the joint relative frequency of those in Town 2 who take a summer vacation, follow these detailed steps:
1. Identify the relevant data from the table:
- Number of people in Town 2 who take a summer vacation: [tex]\( 345 \)[/tex]
- Total population surveyed: [tex]\( 1,402 \)[/tex]
2. Calculate the joint relative frequency:
[tex]\[
\text{Joint Relative Frequency} = \left( \frac{\text{Number of people in Town 2 who take a summer vacation}}{\text{Total population}} \right) \times 100
\][/tex]
Substituting the given values:
[tex]\[
\text{Joint Relative Frequency} = \left( \frac{345}{1402} \right) \times 100
\][/tex]
3. Compute the result:
[tex]\[
\text{Joint Relative Frequency} \approx 24.607703281027106
\][/tex]
4. Round the result to the nearest percent:
[tex]\[
\text{Joint Relative Frequency (Rounded)} \approx 25\%
\][/tex]
Thus, the joint relative frequency of those in Town 2 who take a summer vacation, rounded to the nearest percent, is:
[tex]\[
\boxed{25\%}
\][/tex]
